It will be like bloodborne effect, almost no effect since we knew the game even before E3 so the announcement wasnt really an announcement, hopefully, they'll announce it sooner now we know and put something else as a surprise for next E3, i think they could, they should have much more games coming in 2015, like a japanese game
Predictions for end of 2014 HW sales:
