THough if this U4 is really a masterpiece near from TLOU like most reviews imply, it wont be that hard or a big success to be in the 2-3 best games of the generation seeing how this generation is kinda empty for now for all the consoles in term of masterpieces.
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
