PS4 will be languishing all the way till end of the year, is my guess.
2015 is the year it needs to save itself.
Yeah, IMO they are probably getting ready to re-launch the system during early 2015 (starting with Bloodborne, a first wave of multiplatform games and HSG). This Christmas is already a lost cause. They'll market Destiny, DriveClub and God Eater 2 Rage Burst but they won't try anything impresive.
