For the whole year it's not probably going to sell more than in 2013. In 2013 WiiU actually had pretty good holidays and I just don't see it repeat that.
After 40 weeks:
2014 = 461,349
2013 = 422,612
At the end of the year:
2014 = 618.150
2013 = 898.143
Still considering the starting position to this year it has definitely sold more than people expected.
Wii U this holidays is not gonna sell like in 2013, but will easy beat 2014 numbers, which were pretty tragic.
