We got to look at the Wii U during E3 2012 and, I gotta say, I'm lovin' it. The touch pad isn't multitouch, but it works well. The Pro controller is awesome and very comfortable, and Achievement Support! Also, there is and Online/ Playstation Home type feature. All in all it looks awesome.
No official release date yet, but we expect it to launch in November. Some launch titles are:
Assassin's Creed III
Batman: Arkham City
Super Mario Bro.s U
and a lot others!
