Sony said they stole Nintendos playbook at E3, they explained how they were concentrating on 1st and 2nd party. That they would have the most exclusives per any other system, they continue to buy studios and add people as makingmusic has mentioned. Its worked well for Nintendo why wouldn't it work for Sony? Isomaniac for example is three times the size it used to be, which explains how they can pump out Ratchet, Warhawk and Resistance titles. Ted Price president of Isomaniac is great friends with David Jaffe and helped him set up his own studio Eat Sleep Play. Oh and Sony has signed an exclusivity contract with them for 6 games (which at 2 year development cycle = 12 years) and of course then Jaffe would renegotiate for more money. Sony obviously wants to turn Jaffe into Ted Price2 and Jaffe doesn't seem to mind signing away 10 years of life to Sony so all signs point to it happening.
Sony has shuttered two games The Getaway and 8 days I believe but instead of firing people they have shifted them to other games already in development. Would they pick those 2 IPs back up? Maybe. Anyway Sony said this at E3.
