I don't know how well Forza 2 will do, so I don't think it will push the 360 past the PS3 next week.  But it will at least close the range on the PS3 to between 2k & 1k.  But I expect Trusty Bell to be a sleeper hit in Japan and will push the 360 hardware numbers past the PS3 numbers for at least a week.

Both Amazon bestsellers and Famitsu most wanted have been thoroughly discussed as not being a good indicator of sales. As I understand, the two PS2 games that released last week were in the Famitsu list, and they didn't even break 100k. I think the PS3 is beginning to level out around 7-8k. Will Forza move more 360s? Possibly, it has no where to go but up, right? Will it be significant? Don't think so. But the 6k gap between PS3 and 360 should definitely dwindle.
