I think that there was already a disscution about this topic... I think...
Anyway, I don't think that they'd choose Pocahantas as a world for multiple reasons. To begin with, it wouldn't fit in too well. As nice as it'd be to have one of the older Disney movies in the mix, it wouldn't have a place. Then, there's the historical element. The movie wasn't historically accurate to begin with, so Disney made the second movie as a way to correct the mistakes of historical acurracy, but just ended up making a worse movie that didn't live up to the first, in terms of quality. I also think it wouldn't work out due to the fact that its American History. I don't know why that's a reason, but it probably is...?
Anyway, that's my point of view.
The correct term is Native American. Not Indian.
