Gen 4 remakes are almost guaranteed to happen, its just a matter of when. As for gen 1, please don't do it. We just got the first games on 3ds e-shop. Remaking the blandest and smallest region on Switch is wasted potential.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
