In the week of Black Friday Microsoft sold 750,000 Xbox 360s, wow good week for sure. Sales of the Xbox 360 have hit 70 Million world wide, I'd say the game division at Microsoft is doing rather well.
I had one years ago but traded just the box and one game for a whole wii setup in college ($250 in xbox stuff for $350 in wii stuff). The wii was a better party game at the time. Though as soon as college was over I regretted that trade immensely.
Wally worlds $150 xbox and the $200 kinect deal was what drove this. That was the first time I have seen a brand new xbox 360 new model for that price.
