Since we are pretty deep into Egghead, I wanted to take the time to really try and lay out what we should be expecting for the remainder of the story's Islands. I want to preface that this is NOT a plot thread post (as there is too much to quantify still). Obviously island structure likely won't be correct, but you can make some pretty solid guesses about Islands and its inhabitants if you follow key dialogue and teases in the manga. This was personally how I was able to deduce that Vegapunk would seemingly get his own concentrated arc post-Wano, especially after everything that was missing and plotlines that "needed" to be addressed. Now again, I'm not expecting to get specific plot points right, or even island order (below is just best guess), but I think overarching "structure" may be supported by what we have so far. There could also just be new islands in between these, i.e. possibly an Underworld centric Island or something else.
One thing is all but certain however, when Oda teases a future location, we almost certainly visit said location:
EGGHEAD:
With that I will start that I have no personal guarantees how Egghead will end, but I'm pretty 50/50 on the idea that either we spend the next ~30-40 chapters trying to escape the island while Kizaru is in pursuit, or it lasts another 5-10 with some backstory, etc and the plot with Kizaru continues at another location.
ELBAF:
I'm not 100% sure we can assume this is next, but there it's an extremely obvious and safe location to guess that's coming. Elbaf is by far the most teased location in the series outside of laugh tale. You have the very obvious, early references to the Islands with Dorry/Broggy and Usopp's desire to go there, then Oimo/Kaashi and their offer to take him to Elbaf. Then you have giant at the slave Auction who thanked them and expect to see them at Elbaf.
But even with all of this, the series has done so much for the island in the past 200 chapters, ranging from it's culture to namedropping a key character (Prince Loki), to giving us hints of it's structure (an impossibly large tree). It's also here where I think Urouge will be central, or at least in some form in connecting the Giants to the Sky People, Lunarians and Moon Lore. Honestly, I'm not sure if this is Shanks' territory yet or not, so I don't have much to say there. But, thematically, if it is, then it at least provides Shanks with his own base of operations, like Blackbeard with Fullalead.
FULLALEAD:
Another obvious location in recent times. Firstly, its BB's headquarters, and as such it stands to reason that we probably will visit it just like we did WCI and Wano for 2 prior Yonko.
That being said, I think the Island means more than just a main spot for a Yonko. It IS Pirate Island, which has been centered around things like the Davy Back Fight, Rocks' initial crew, and what I believe to be the central location for silver medalist players still in the game. Yes, this involves a huge conglomerate of former Whitebeard and Roger pirates, former Rocks pirates such as Ochoku (who may still serve Blackbeard) /Silver Axe/Shiki, and Impel Down Escapees.
Not to mention, you have the current Koby incident that is about to spark a serious fight on the island.
The main question is, between Fullalead and Elbaf, which one happens first?
GOD VALLEY:
Now this is where we start getting into a bit of uncanny territory, but if we follow the same logic as mentioned above, God Valley IS a topic that will be visited. The question really becomes when and if its a physical location? God Valley is interesting not only for missing Rocks lore, but for the fact that the WG erased the island from maps is an important note to make. Why was the Island "erased"? What was there? What was the purpose of doing so?
Now yes, we seem to know what the WG does when they "erase" islands (they literally seem to destroy them as with Lulusia), but I wonder if that's the case with one considering its lore significance. Otherwise, we may just witness this in a Rocks flashback in the future. Anyway, if it does still exist, I would place my bets it's visited before Laugh Tale, but I have openly campaigned on it being the last island potentially in the series (post final war). Just not sure anymore.
LODESTAR:
While it doesn't hold deep lore significance anymore since Inu had essentially spoiled it's purpose (to inform the visitor of the RP's), I think it's still fundamentally important to visit considering, like God Valley, it is teased signficantly.
Also, as of writing this post, I've come to the realization that Laugh Tale still may be near the geographical end of GL, but there isn't a sense of navigation beyond Lodestar. If this is the case, then Lodestar is 100% necessary and we must land there in order to continue to Laugh Tale.
I think Oda's conveying of this is a bit confusing, but you can see in the images below that all routes all converge to Lodestar, THEN another arrow heads towards an X spot.
LAUGH TALE:
Which really brings me to Laugh Tale. I don't have much to say here, only that it makes sense that post-Lodestar, the crew continues to head in an unspecified direction "east" towards the end of Grand Line, to Laugh Tale. I actually don't believe it's in a random location earlier in GL, just a place where the log poses do not work anymore.
Geographically, it may still likely be the "last" island on GL.
NEW MARINEFORD/MARIEJOIS:
Again, if we take into consideration proposed structure of the narration, then these locations being last make the most sense.
- First, you must take into account that One Piece needs to be used for "Something".
- Second, that "something" aligns with WB's death speech, which suggests it's discovery (and the knowledge of the Void Century) will spark a global war and the downfall of the WG
- Third, you have clear teases to Ancient Weapon usage. Firstly, Shirahoshi is Poseidon, and is at Fishman Island. Roger arrived too "early" because she wasn't born yet. Second, Pluton is buried under Wano, whom needs to open its borders to be unleashed, which has not yet happened. Uranus is missing still, but it stands reason assume they must be used with One Piece.
- Finally, you have the Madame Sharly's prophecy, which suggests Luffy will destroy Fishman Island. This, in fact, may be true, if the idea that Red Line is meant to be destroyed (and Mariejois with it). This also coincides with Noah's intended use with the Sea Kings (clearly Poseidon is meant to direct them to use it at least). This may also be highly central to Jinbe and Sanji achieving their dreams.
- As a bonus, both locations have been teased
Now, I have zero clue how they would go from Laugh Tale to halfway around the world in a reliable fashion, or if there is even a means to doing so. I can see the crew finding and taking High West (if it exists in the new world) back west towards the final war.
Beyond this point, I personally don't know. I wouldn't expect there to be anything else, but you never know with Oda. However, I believe these islands are almost guaranteed a visit or arc relevance, with possibly 1 or 2 additional islands somewhere on this list.
TLDR: One Piece's remaining islands are:
- Egghead
- Elbaf
- Fullalead
- God Valley (maybe)
- Lodestar
- Laugh Tale
- New Marineford
- Mariejois
with some other possible islands in between several of these (i.e. an Underworld Arc if its not one of these, "Emerald City", another Sky Island or Moon Arc). It may seem like a lot, but even Egghead is seemingly ending quicker than expected (maybe).
