I don't consider it to be a possibility IMO. I don't think there's a lot of potential in using the same world a 3rd time, but what I think is that Unova lends itself very well to a Legends Arceus-like prequel game. It would explore Unova 1000 years before Black/White. And I feel like the Pokemon Company has to have seen the potential here too.
So my prediction is: Black and White remakes, maybe Black 2/White 2 remakes, and possibly a "Legends Kyurem" game
I wish, with 1+2 releasing on Switch, and some sort of Legends game, but we’re probably going to get a BDSP style remake of just B/W1, and then a Legends game. I don’t expect much from TPC and Game Freak anymore.
Highly unlikely. GF wants as many people to buy this game as possible, and I doubt they’ll tie its story to 10+ y/o games that they don’t even sell anymore.
