You think the next game would be one that combines all regions, on the nintendo switch? (potentially an mmo of some sort??
That would be awesome, but it isn't very likely because they would make more money by releasing individual games rather than all of them combined into one (and it would probably be way easier). I think that the next game will be the 8th Generation game and it will be an entirely new region, maybe with another region accessible in it as well. If they made another region accessible in the 8th Generation game I think that would be really cool and also has a decent chance of happening!
