No Gen V's gimmick is Hidden Abilities. Also there's a high chance they're not doing away with already-made assets. Makes a game company look dumb for doing so!I really hope Game Freak is keeping their ears to the ground and can understand the fans' palpable Gen 1 fatigue, and decides against featuring Mewtwo for yet another generation.
This is just my opinion (from an old fart who began with Yellow), but I want Gen 8 to get away from Z moves and even mega evolutions entirely. I want it to be a soft reset and focus on evolving the turn-based mechanics, akin to 4th gen's physical/special split. We have received gimmicks for three generations in a row without any significant tweaks to the core mechanics, so I think a major change every four generations makes sense.
Generation 5 was triple battles, which didn't last. Gen 6 was Mega's, which is on life-support after receiving no new ones in Gen 7. Gen 7 gave us Z moves, which I can only hope to god is left in Alola. The exception to this trend is Alolan Pokemon variants, which obviously should become standard going forward, breathing new life into old or neglected Pokemon.
My personal assumption is we'll see the name of each version, the three starters, and a brief glimpse (give or take less than a minute) of gameplay.
And Ultra Necrozma needs Ultranecronium-Z to become what it is so they aren't doing away with something heavily integrated into its lore, which in return, does make Z-moves hightly likely to return.
