Even if they are "huge" successes (Uncharted having the best shot) they'll dropping in months that have room cleaning, floor shattering games like Halo, GHIII, Rock Band, and Mass Effect. They need room to breathe that they just won't get. The multiplatform hits this fall, as Madden has shown, will not be moving PS3s to any significant degree and the fact that there are SO MANY of them this fall (Assassins, COD4, Rock Band, GHIII) is going to make it so hard for those PS3 games to stand out. GT5P will probably have the best shot because regardless of content, it's going to look to your average consumer like a really awesome budget priced game. But will that move consoles? Probably not enough.
