Just googled it,i now know what it is. Sorry for not understanding at first.
The Wii U...... basically the new Nintendo Wii.
If im honest, i dont think it will offer us fly boys anything at all. Its aimed more for the family gamer and more casual people where as the 360/PS3 cater for the more serious gamer.
At best i'd say the clost you would get to "hardcore flying" on the Wii would probably be ace combat or something along those lines.
Then again i could be wrong, but those above are just my thoughts.
Birds of Steel is due out before long and i'll be playing it religiously on my 360
