I don't think so. The WiiU has the first console advantage (you can see what that did for the 3DS and 360), and we know nothing about the other consoles. Both of those could use a tablet controller also! And the WiiU seems to be getting 3rd party support, and DQX in Japan automatically gives it a 1-UP over the competition.
I think we'll see (after 5 years launch-aligned):
WiiU-85mil
PS4-78mil
720-63mil
I see the 720 being over-expensive and late, so won't pick up sales easily.
