I ned to ask obieslut.... what period are you classing as December.
There were 3 ways of looking at it last year (2 are in my previous post... sulla has the other one)
This year there will only be 2 ways.
1 way will be the 4 weeks ending the 27th December and the other way is the 5 weeks ending 5th January (same as NPD should have I think, but then this is Europe so not NPDs territory)
Either way the PS3 will not get over 2 million never mind 3 million.... you realise numbers can lie, you have to think about what the best comparison is to be fair rather than just comparing, otherwise you could compare PS3 to PS2 from worldwide launch and show that the PS3 is almost equal to it, or Crazzy's thread where he compares the PS3 now to the PS2 in 2002 (which is unfair because the PS2 was much younger in 2002 by region than the PS3 is in 2008)
