So do you have codww2 on ps4? if yes please look at the highscores and tell us how much players are registered, i mean with all that factors which where told here why the xone version has ~ 10 million "players" (5.6 million retail source vgchartz) there should be between 22-24 million players on ps4, if not i think the digital attach rate on XOne in the big markets is much higher than on ps4
