I don't think they will be happy with everyone buying their multi-plats on the PS4, the console already can't play a current-gen game (Tomb Raider, MGS etc) at the right settings
If they had it their way, I reckon they'd release a new console next year as ever since the XBO was revealed it's been a disaster. Pretty pissed off still as the 360 was probably the best console I've ever had.
