Sony has a huge amount of first party studios. Many of them have made alot of recognized franchises through time. Syphon filter, Wipeout, Medievil, twisted Metal, God of War, Gran Turismo, ICO games, Ape Escape, Crash Bandicoot, jak & Daxter etc. etc.
Sony does rely on their first party game studios, and they will be handing out more through time.
Contrary to Microsoft who hasn't established nearly as many first party franchise really, besides Halo, Fable, PGR & perhaps Forza. Besides what on earth makes Microsoft sell their internal studios? wtf
Since microsoft isn't entirely succesfull on that part, they feel obligated to go to high profile studios and buy out exclusivity. Microsoft depends on their exclusives. They aren't really providing anything magnificient from their own internal studios.
