This feels like this year's version of the Doom/wolfenstein announcement, where it caught everyone off guard. The fact that this will be switch console exclusive (at least for a while) tells me the chances of getting a GTA V port is still there.
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.
