Just wondering what people think about this mainstream theory at this point in time.
Most likely, as it is a fight that has a decent amount of build up. Even in road to laughtale it is mentioned that
the people who are connected through scars are destined to meet again.
- shanks got his scar from teach
- warns whitebeard about teach, shanks most likely knows about the will of D and knows that something is fishy about teach, and he also knows how strong teach is as he managed to put a big scar on him
- his jolley roger has his scar in it for some reason
- Teach says in marineford that "We are not ready for you yet" could be implying that they will clash in the future
- I think the pirate he wanted to talk to the gorosei about is probably teach
Shanks is too strong to stay alive till the final war as he obviously is going to ally with luffy
That would make the alliance more bloated than it already is.
A clash between shanks and teach has a good chance of happening. Where teach would kill him and this would set an even more emotional connection between luffy and teach
Or
This doesn't happen and oda takes a completely different route
