I disagree, If you look at the whole picture, GoW3, KZ2, MAG, Little Big Planet, Motorstorm 2, RFoM2, they left a huge impression. They have more games lined up for us that are great.
The only thing M$ been doing the last 2 years that were huge announcements were GTA IV and FFXIII multi platform, deal with it, that's all M$ had to show. Other than those 2 announcements for the exception of BioShock and Gears of War 2 and the last installment of the Halo trilogy, they ain't got anything else that Sony has.
Keep this in mind, Sony will always have the most exclusives, most of their exclusive games are the biggest name in gaming history.
Gran Turismo God of War Rachet & Clank Sly Cooper Twisted Metal MGS Kingdom Hearts Tekken
and many more,
now what does M$ have as the biggest Exclusive?
Halo franchise is done, the next halo games are not going to be huge. Gears of War, there will be an end after 3. What else do they have that is exclusive that are famous?
Don't worry I'll wait.
Moving on, Tokyo Game Show is going to be very interesting, we will probably see more about GoW3 and possibly MAG.
