From the looks of it, the "other" territories are raising the 360 attach rates, but the American market has better per console sales for both games on the PS3. I estimated other by subtracting the American from Worldwide.
Edit: The American numbers are the only solid data numbers from this site. The others are approximations.

It seems the mods need help with this forum. I have zero tolerance for trolling, platform criticism (Rule 4), and poster bad-mouthing (Rule 3.4) and you will be reported.
