Based on NPD, November 360 sales in JUST the US alone (not full Americas) was 14k higher than the VGChartz estimate.  Very close estimation, ioi, I applaud you.   What this does show, however, is that some adjustments of maybe ~25k+ should be made to the 360 number and likewise a decent chunk removed from the PS3 number.  Xbox 360 still wins November over the PS3 even with Black Friday sales?!

Also, MW2 was a beast and 360 version sold 3x PS3 version in the US (not unexpected).

November 2009 Hardware Sales

• Nintendo DS -- 1,700,000
• Wii -- 1,260,000
• Xbox 360 -- 819,500
• PlayStation 3 -- 710,400
• PlayStation Portable -- 293,900
• PlayStation 2 -- 203,100

VGChartz Hardware data for the period 01st Nov 2009 to 28th Nov 2009:

Console	PS3	X360
America	840,249	805,161

Is that really from 1st Nov? I thought the chart started at Oct 31..
