I am not sure about this whole no third party support thing, this is just plain false. there are already plenty of third party games so far, and it is just one month in. Already in the launch window many franchises have launched which have not been on Nintendo consoles before such as Assassin's Creed and the new Ninja Gaiden series. There is already going to be greater third party support than what was had on Wii, and significantly greater support than what was on GameCube and N64. Ubisoft, this generation, looks to be shifting over to Wii U as their main console, the only ones who probably won't are EA/Activision/THQ - but they're still showing greater support than they ever have on an Nintendo console.
Anyway, what I think their biggest obstacle will be is marketing the Gamepad the same way as they marketed Wii Remotes. It's much easier to hand out a bunch of Wii Remotes and give everyone a try. Not so with the Gamepad. It will be much more difficult.
I describe myself as a little dose of toxic masculinity.
