Does Sony have a bigger game after the God of War 3 release?

After God of War 3 does Sony have something bigger planned for the rest of the year? There are rumors of the sequels (Killzone 3, Resistance 3, and Infamous 2) but they are not bigger franchises than God of War. Is it a mistake to have this game come out in the spring? I think the game if it came out during the fall they would sell more consoles during the hollidays.
