This is what most fanboys fail to understand... Halo 3 might not have the best graphics, but has the best gameplay, and that's why it's one of the most popular online games ever.
Hummm... for all we know it could be another MGS for the Iphone.
As for Microsoft i expected more from them. They didn't show anything. Last year Microsoft announced Fable 2 and Gears 2 at GDC, this year nothing.
The first half of this year, the x360 got good exclusive games like Tales of Vesperia (in Europe), SO4, Halo Wars, GTA4 DC, Race Pro, etc ... but the 2nd half of the year, there is nothing exclusive anounced from Microsoft. Guess we have to wait for E3...
But... but.... Sony does not pay for exclusives...
Blind fanboys still believe that Sony does not pay for exclusives (probably believe in Santa Clause too).
Every company one way or another pay for exclusives.
