In short terms Patcher's comment on Wii U failing is based on the small info we have that the Wii U might be priced too high. Nintendo has in fact insinuated that the Wii U might cost more than people expect, and Pachter's point is that Nintendo should come out and retract that statement and explain to people that the Wii U will be affordable.
Then he says that Kinect would kill a $249 Wii U anyway, which I can't explain why he said such a ridicilous thing.
Then he claims that Wii owners have gone on to FarmVille, but by the same logic I don't understand how he thinks Kinect users wouldn't have gone to Social gaming.
The 4GB HD's in Nextbox and PS4 was probably just a slip of the tongue.
