It's not sold out everywhere, but there are some shortages.
Go to Gamestop.com and do what I said, see for yourself. I checked 360 pro and only one location out of about 20 had any, all others showed 0. Then I checked PS3 and every location had 1-4. So the system isn't broken or anything.
As I say, it's not sold out everywhere, and I agree if you're willing to look around you can find one at brick and mortar, but there are still spot shortages particularly on the Elite sku but even the Pro.
This makes me think 360 might have a big February as supply fully catches up (assuming that even happens).
