>Customization>3D-fication of the overworld>acknowledgement of the competitive scene with the new breeding mechanics and super training>rideable pokemon, particular surf models, soaring>pokeradar and then dexnavGen VII:
>still customization, most likely with more options>improved overworld, no more chibi models>introduce hypertraining>variety of rideable pokemon confirmed (maybe soaring returns not limited to eon duo?)>rotomdex, while it could enable some hand holding, could also have great features>battle royaleassuming the rotomdex keeps some of the functions of the dexnav, which is reasonable, I'd say so far it's a straight up upgrade from genVI's positive things.
seeing how it's the 20th anniversary, I think the post-game will be a little plot-driven thing like the delta episode and a good battle facility, at the very least.
bottom line, it won't suck balls. depends on how many content and features are, it will be anywhere from "decent but underwhelming" to "top tier pokemon game"
