Some people seem too confident that X1 will easily reach more than 30M, it's already fighting to reach more than 200k every month, so let's say, by incredible luck, X1 sells 4M each christmas ( which is unlikely with such domination , and more the PS4 will dominate, less the X1 will sell ) , in 5 years, it could reach 40M yeah, but it wont be easy at all, it's not crazy at all, at the opposite, to think about 30M Lft
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
