Yeah they have a great lineup this year. It's too bad there were so many no-shows though, such as The Getaway and Eight Days. Maybe we'll see those at TGS this year or some other event.
And yeah, devs are starting to see the benefits of making PS3 the primary development platform for their third party titles. Rumor has it that EA will begin using PS3 as the lead platform starting with Madden 2009 next year. And the deal with Epic that optimizes UE3 for PS3 should yield some great results as well from games that use that engine.
