we know from france gfk the ps3 has been outselling the xb360 ~2.8:1 (no doubt over 3:1 now since this was before xmas).But he didn't say "PS3" outsold 360 3-1" he said "We" outsold 360 3-1. And Sony has made misleading PR statements before.
Personally I'm not sure. I could see sales evidence for both interpetations.
also if it was ps2,psp,ps3 against xbox the ration would prolly be at least 10:1.
the ps2 has very long legs in PAL countries
