Ahem, 15. Speaking about the strength of the PS3's lineup Tretton commended the exclusive third party titles such as Rockstar's Agent and Square-Enix's Final Fantasy XIV alongside the 15 in-house titles being developed exclusively for PS3. These don't even include second-party releases such as Sucker Punch's inFamous and Insomniac's Ratchet & Clank: A Crack In Time. It kinda makes you wonder what else is in development - we assume he's including Starhawk and David Jaffe's project in his list — but what else do Sony have up their sleeve? We wouldn't be surprised if a new Killzone was announced next year.
