The one comment I absolutely hate is "it needs to outsell WiiU/3DS combined" to be successful. No.
That's ignoring the fact that 3DS struggled out the gate, and it had to receive an 80 dollar price cut mere months after launch, to get it going. That's a lot of revenue lost.
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.
