Hard to say really ...
With the Wii U being a new platform and with it will have a limited userbase to sell to, and with the launch line-up looking as strong as it does there will be quite a bit of competition for these gamers, but there aren't many FPS games and there are few "mature" games with as strong of an IP; so I wouldn't be surprised if it sold 1.5 million units by the end of 2012 and an additional 1.5 million units in 2013.
