>>28708730I'm gonna make the safe call and say that they're gonna be more polished versions of XY.
XY's transition from 2D to 3D was a little shaky, there was definitely work that needed to be done on character models, while the pokemon themselves look fantastic imo.
looking through the trailers, everything about the game screams *XY but better!* with tuning up mechanics like expanding on Pokémon Amie with the new Refresh, having new powered up moves to compliment powered up forms with the Megas, and so on.
I don't think it'll be a gen that breaks the mold or sets a new bar, more like everything XY has done to bring Pokémon to the 3DS, then polishes it for a smoother, more solid game, which I'll appreciate.
