It doesn't matter. We were literally told OP is in its final arc and is ending in 3 years. Oda will find a way to tie all storylines together.
Obviously it won't be easy to predict how it will happen, but if I were to guess:
The final poneglyph is on elbaf, the marines and the WG get to the poneglyph before Luffy or the pirates. The final poneglyph is taken to mariejois.
In order to get to it, Luffy allies with Dragon and challenges the WG to a war. Teach shows up and decides that he is going to genocide the CDs and become king of the world. Luffy fights teach to stop him.
I'm sure my specific prediction has some holes in it, but that's not really the point. Its that Oda can and will tie all plot points together. He said this is the final arc, let's stop pretending as if he's lying.

Blackbeard moves out to acquire the Poneglyph rubbings
He and his crew go to Shanks who have one
Lafitte and Shiryu don’t come with Blackbeard instead go and take law and kids rubbings
Blackbeard and his crew have all the poneglyphs except the WCI one which Luffy has
In the meantime, Crocodile gets a report from Caribou, where Pluton and Poseidon is. Cross Guild goes and claims them then attacks the world government with them. Cross Guild now becomes the leaders of the world
Meanwhile, Luffy and crew follow their log to the next island but run into Sabo and Vivi on the way. Sabo explains what happened at the reverie and that Kuma told them to go to Vegapunk and have them a vivre card. They go get lore, marines show up, Vegapunk has a direct water way to an island he did a lot of study on called the Rainbow road, crew ends up in Elbaf. Luffy and Usopp hear about what happened to shanks and his crew on Elbaf, leading to Usopp development. Luffy and the crew decide that they’re willing to fight Blackbeard for Luffy to avenge shanks.
Blackbeard vs Straw Hats battle
Straw Hats take the last Poneglyph go to raftel. Robin finds the rio Poneglyph and reads the true history saying what the one piece is and that it’s in Mariejoa.
Whereas Roger laughed because the ultimate treasure was out of his reach, Luffy will come to a different conclusion and prepare to attack the world government.
Grand fleet reunites and final war begins ending when luffy destroys the red line and fishman island below.
Then we’ll get a final scene of luffy going to shanks’ grave and laying the hat down upon it.
Epilogue chapter of like “20 years later” we were told OP was in the final saga. And for context the baroque works saga and summit war saga (you know Sabaody -> Post Marineford) was barely two years.
