Oh I'm pretty sure he already did a lot of stuff he wanted to do. Weak hardware was never the reason for introducing UBs or Z-moves.
I do want to believe Pokémon will make a return to form on the Switch, but it's just impossible with that guy in charge. I have absolute zero trust in him, with the 3 games he's been involved with being by far the 3 Pokémon games I most dislike, and all of them having introduced very crappy ideas (which can't be thrown away in later games because this is Pokémon).
I do think Sun/Moon are alright games on their own, 7.5ish maybe. It's the additions they make to the franchise that make them so hard for me to swallow - on the other hand, OR/AS are just plain terrible.
Well, the Switch has been doing well in terms of improving franchises. I'll be optimistic surrounding Prime 4 and Gen 8, but we'll see what happens
