Bout damn time! Sony has been waiting for this epic day to finally unveil Team ICO's next game. They've been waiting just for you!
Here are my recommendations:
Day one buys:
MGS4
Uncharted
Games to get a little bit later, but must haves nonetheless:
Ratchet & Clank Future
Heavenly Sword (though I'd wait for it to go Greatest Hits. It's a great game, but at only 6 hours long, it's not worth $60)
You may want to get Resistance as well, but I'd just wait for Resistance 2. Or better yet, Killzone 2 (I'll tell you why ;)).
And then LittleBigPlanet and Valkyria Chronicles should obviously be purchased over the next two weeks.
You can check out my PlayStation 3 exclusives thread to see more titles that have recently come out or are coming out in the near future. All dates for Blu-Ray disc titles should be 100% up to date, but the PSN titles may be a bit off. Quite a few should have been moved to the 2009 list by this point, but I'll get to those later this week.
