So you're expecting Xbox 360 to be down by 35% compared to last year?

Yeah.

The 360 sales of the last two weeks were exceptions due to MW2 Bundle and Walmart deal.

Now the sales it should be below last year. About 30% I guess.

L4D2...

2 million and 1 (the 1 is mine for my beach house)

Although an excellent game, L4D2 doesn't have the selling power of a price cut-deal and MW2

Great game but not a system seller.

Hard to say, probably around the 1-1.2 million mark, I'm on the somewhat conservative side since we don't know a number of things;

A: How big will FFXIII be in Japan?

B: How well/poorly will the PS3 do in the US? The 360 having a great holiday there is a given. after all.

C: What about Europe? Europe is quite divided with some countries buying zounds of PS3's and others buying zounds of 360's (UK for instance).

If I have to peg one number I'll say 1.2 million, if only for the fact that I think FFXIII will be a monster in Japan and drive hardware well beyond 100k, possibly 150k.

1.5 - 2 mil, Japan will help out there....alot

In the Americas it wasn't doing much worse than last year before those weeks, so I really don't see why the holidays would be much lower. I think it will be somewhat lower because of the bigger competition from PS3, but nowhere near 30% down. And since the Americas are by far the biggest market for the Xbox 360 its performance there will be decisive for its worldwide performance as well.

Before these weeks (MW2 Bundle and Walmart deal), the 360 sales were down around 30% or more comparing the last year.

-23% at the Week End 31/10
-35% at the Week End 25/10
-32% at the Week End 17/10
-31% at the Week End 10/10

This is real 360 sale for this Holiday.

For example, I expect sales around 290k for 360 this week (end 21/11) and this is 27% below sales of 2008 (400k at same week). And PS3 should be up to near 400k this week.
