Well, we could compare the 360 of this week to the Ps3 in the exact same week last year.
Week ending 11th/12th December 2010/2009
X360 (2010): 726k
Ps3 (2009): 743k.
The Ps3 then jumped to 1018k the next week. That was, however, largely boosted by the launch of Final Fantasy 13 in Japan, which seemingly gave the Ps3 an extra boost of ~ 100k there. As the X360 doesn't have any game that will provide a similar boost next week, this anecdotal evidence suggests that the X360 will fall just a bit short. 950-ish k.
Or we can just compare the X360 of 2010 to the X360 of 2008.
Week ending 11th/13th December 2010/2008
X360 (2010): 726k
X360 (2008): 700k
The X360 then jumped to 906k. The X360 of 2010 doesn't have that much more going for it than it did in 2008. Sure, it has Kinect, but the Kinect also boosted the sales in the week ending the 11th. Why should it boost the sales for next week, more than the sales were boosted in 2008?
If we just do it statistically platform by platform over the past 2 years, here's what we get.
The X360 needs a 37.7% boost in sales to achieve 1 million.
In 2008, the machies had the following change between week ending 13th and 20th.
DS - 26%
Wii - 23%
X360 - 29%
PsP - 36%
Ps3 - 18%
Ps2 - 23%
Only the PsP came close, and that was with the release of Dissidia in Japan.
In 2009, the machines had the following change:
DS - 17%
Wii - 17%
Ps3 37%
X360 26%
PsP 22%
Ps2 19%
The only one that came close was the Ps3, and that was with the release of Final Fantasy XIII in Japan. It wouldn't have been over 30% if it wasn't for that.
So overall, I'm going to say no. I see a boost of around 30%, which translates to roughly 940k next week.
