I'm just going to tag this thread to have a good laugh from it in a year. These systems are going to sell very well and possibly sell in 4-5 months what Wii-U will have sold in it's first year. People have been waiting for several years now for these devices to arrive and Wii-U is no comparison because for these consumers that device is not even a option(aside of maybe buying it as an extra in the long run).
To sum it up really simple: A lot of PS360 owners are going to buy a Ps4/Xbox One, Most of the current Wii owners are not going to buy a Wii-U(because they bought it for the motion controls). If Wii didn't have motion controls it would have sold like the Wii-U is selling now and the PS3 and X360 would still have sold the same, possibly more.
Wii-U sales are no indication of the possible succes of the PS4 or Xbox One. Saying so is like saying the next Iphone or Samsung S flagship smartphone is going to sell bad because a mid range model smartphone of a Nokia smartphone isn't doing well. It's not catering to the same market segment and it can in no way be compared in demand.
