I could see Nintendo going the apple approach and releasing the Wii U in October. Given that they are advertising the Wii U already means that they wanna release it soon; don't want people to loose interest in a console if they don't know any information about it or if the launch is months away.
Plus Ubisoft has stated that they are going to support the Wii U in a BIG way, its not to far fetch to release AC III on the Wii U a bit early as part of their support.
And regarding the price of the Wii U, the $300 price was the expected price. A second SKU with Nintendo Land makes sense since they wanna sell the game like crazy.
Just saying that the information given to us is not out the realm of possibility.
No regarding the F-Zero rumor, that would be amazing if true.
Also note that this is MY opinion, so please don't go bashing me like crazy. I just think that this is something that
could happen.
