@towolie: A lot of those things were said about Wii pre-launch. We are now months into the Wii U and sales have been low. The current state of Wii U is sad compared to how the Wii was selling at this point in its life (as in sold out everywhere). I don't really remember people saying PS3 would fail, just that it was too pricey and needed a price drop - which was true and happened.
Point is, Wii U isn't doing so hot. I bought one. Haven't played it since the week it came out. I have buyers remorse like a Move/Kinect owner.
