Looking at my own region I think Sony may well be correct that the PS3 is currently the best selling console in Europe, quite a few people I know bought a PS3 just recently.
Hopefully we receive reliable data from the US as well, before the PS3's release I had a bet with someone as I was expecting a global sales victory versus the XBox 360 for christmas 2007 (not 2006 and not against the Wii due to pricing).
