The scale of the game is so ambitious, i've never seen that before in a shooter, Uncharted 4 seems to be for TPS's what GTA V is for open worlds.
Rockstar and Naughty Dog are really the 2 developers on the top, with Square Enix maybe, depending on FFXV.
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
