that's not what you posted, if you're not going to stay coherent in your arguments then we cannot have a coherent discussion. Right the old port test that publishers are known for.
I never stated that it won't get support, completely different I acknowledged that it would get more support than the Wii, however my entire point is that it won't get premier software support and its unlikely to get more support than 3ds and PS3 which will seriously hamper its possibility to establish itself as the dominant platform once its the fist next gen console released. Yes I do think Wii u is next gen.
My point is that because the competitive landscape has changed the Wii U is unlikely to become a dominant force in japan, the 3ds is too strong and the PS3 and mobile are viable enough as platforms to make it likely. The software support is better than Wii, but lesser in comparison to what's available on the 3ds and PS3. In japan the audiences have proven time and time again that they are OK supporting handhelds and old consoles until the new ones become viable, which will trow a wrench on the expectation that the Wii U will become the de facto console or platform.
This is my opinion, I do admit I can be wrong, but I haven't seen anyone presenting arguments besides "its Nintendo, its gonna be a slam dunk, ports of games already present in cheaper platforms and better support than Wii"
I think that in order for for the Wii U to dominate in japan, it needs better than what I've seen so far.
About PS4? Who knows, we have 0 official details about that, however I don't think Wii u needs to worry about that in its first year. They are competing against 3dsxl/mobile and Ps3.
