I don't think we can accurately predict Christmas sales yet. We have no idea what the software lineup will be. I do bet that Nintendo will have more supply this Christmas than last.

PS3 beat 360 last year because PS3 just had a $100 price cut and everyone waiting for a sub $500 ps3 finally bought one. This year there will probably be a decent 360 price cut before the holidays in NA which will help it a lot. There is very little chance of PS3 getting a price cut this year after the financials sony just released. So PS3 probably will beat 360 WW but not by much.

Wii >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> PS3 >= 360

they will definitely have more supply for this holiday

Wii Sales will be way up on 2007.
PS3 sales will be impressive compared to 2007.
360 sales will be similar to 2007 holiday sales for it.

still no one explained to me why 360 can't sell as well as the ps3 this Xmas.

@toastyJaguar

Because PS3 SOLd MORE THAN 360 last Holidays despite 360's mega-superior line up

THIS YEAR

PS3 has the superior lineup....360 doesn't have HALO 3....

simple as that

well maybe the trend will continue but work for the 360 this holiday then.

seems that the console with the inferior line up sells the most... whey!

 so that's Infinite sales of the Wii. 8103.08.... PS3s and 1 X360 sold.

Wii:

PS3

360

 Because it was a 300% increase without Europe, and without a massive price cut, it wont double or anything like that. It sold 4.6 between September and 1st week Jan, so I would expect closer to 5.5 or 6m
