After 2013, i think it has 0% chance to even think of reaching Gamecube's LTD unfortunately.
This year will be its peak year with ~4.5million WiiU's shipped because of a decent but short lived boost through Smash and Mario Kart.
Next year things will start to get even more ugly with The Legend of Zelda pushing a few more consoles totalling ~3million for the year.
In 2016 WiiU will be on its deathbead most likely and will be discontinued that year (or not and in 2017 it will sell an incredibly low number for the year). Add some 1.5million to its LTD.
All in all, going by what i said WiiU will finish its life with ~15 million shipped. And im being optmistic about this year's boost.
