PS2 was outselling X360 pretty consistently until August. However, starting with the week of September 8 X360 has usually been in the lead, with two exceptions. Since PS2 keeps sliding down, I think X360 has it for the foreseeable future.

It's possible PS2 could get ahead of X360 regularly again, but if so I don't think it's going to be in the next month. Star Ocean 4 is a pretty big X360 February release.
