Jack Tretton has just announced that Assassin’s Creed: Brotherhood will feature an exclusive beta for PlayStation 3 owners. This comes on the heels of other exciting exclusive announcements for the PlayStation 3 brand.

Additionally, not only can we expect the multiplayer beta for AC:B, but we can also expect exclusive Limited Edition bundles for Dead Space 2 (with full move Support) and Medal of Honor. Considering Microsoft prides itself on delivering exclusive DLC and content to its userbase first, this is a huge blow against the competition.

It doesn’t stop there either. Gabe Newell has also revealed that Portal 2 will have its best version on the PlayStation 3. While the big man is usually seen eating food, this time around he was last seen eating his words on the Sony stage — finally. Don’t worry though, we’re sure we’ll see more from Valve and Newell as they are a great company in terms of quality titles.

PS: Don’t forget the many hours of exclusive content that will be featured in Mafia II as well!
