I honestly think that GT5 is the only system seller and it will face off against Halo Reach
The GT franchise is popular but the Halo franchise is crazy.
I predict mega sales for both consoles with maybe the PS3 slightly edging it. But only slightly.
2 million consoles to be sold for each with the winner maybe grabbing an extra 250,000 sales.
With BluRay seemingly destined to never be adopted by the mainstream the only thing that differentiates them is Free Gaming for the PS3.
