I've wanted one for Shanks and his crew forever but I'm losing hope for it. Lodestar kinda sounds like Lonestar which gives me vague hope too.
Still interested to see how Oda tackles the last ~2-6 major antagonists, assuming Blackbeard and Akainu are at least guaranteed. Shanks could go either way (for now) and Im may or may not be powerful. Rocks may or may not be alive still either, which could be a factor. And I'd say Kizaru/Vegapunk stuff may somewhat be separate from other things like the final war, assuming there is still this marine interest in Gigantification (it'll be interesting to see where his secret facility is since it's not at New Marineford/Mariejois). I've constantly vouched that they may be tied to Elbaf with BM's remaining plot
Granted there also could be some other hidden antagonist besides this, but I hope not...
