If the slide pad is anything like 3DS, I am not a fan, I don't know why they just didn't go with normal analog sticks. Even though one of Wii U's main purpose is to get multiplatform games and 3rd parties on board, I would still buy the games on Sony or Microsoft's platforms, mainly because I prefer normal analog sticks and I don't trust Wii U online infrastructure. I expect Wii U 3rd party support to be similar to GameCube, it will get some multiplatform games like GameCube did, but Sony and MS will still end up with more multiplatform games, as well as the multiplatform games selling more on the other systems. Wii U will be strongest for it's 1st party support, just like every Nintendo system.
