My predictions for Microsoft E3 were Forza 7(obviously) for Scorpio launch, Halo 3 remaster also for scorpio launch, Halo 6 for fall 2018, and a long lost IP, probably one of Rare's for spring 2018. This might be the that game.
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.
