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.

You're too focused on the worldwide percentages and the assumption those will remain constant within the next few months. Sales trends differ from area to area so worldwide percentages will be influences by those as well. As for comparison to earlier years, Xbox 360 even sold more than 2,5 million in 2007 when it didn't have a great holiday like last year.
