No game this year will boost sales better for the PS3 than Metal Gear Solid 4. It was an established franchise with a dedicated and established fan base who waited a long time for it. I think its boost approximately matched Halo 3's boost from last year, but it is hard to say for sure due to seasonal differences.
I think the PS3 will sell about 11 million units this year, and the Xbox 360 will sell about 8 million units. If you look at holiday sales from last year, the 360 crushed the PS3 in each month. I think, at best, the PS3 will match the 360 during the holiday season.
