Smash 4 is also on 3DS, though. That'll help the game's sales, obviously, but I wonder if it might end up hurting Wii U sales. It always used to be that you'd end up having to buy a Nintendo console at some point in the generation if only so you and your friends can play Smash, but now, if you've already got a 3DS, you can get the same experience without buying a new console (Granted, all your friends also have to have 3DSs and their own copies of the game if you want to play with them, and it's definitely not the same thing as playing it on the sofa on a big TV, but still, I wonder if it might be close enough for some people who might have bought a Wii U if it had been the only option).
