According to this Reuter's
article,
Microsoft has only sold 600,000 Xbox 360's in the US since it's launch
on November 22nd. That number seems about right given the numbers
that have been floating around on the internet for the last two
months. That number does not include the roughly 250,000 units
sold in Europe or the 10 units sold in Japan (I kid, I kid). John
has already seen a few of the 360's on shelves so hopefully every one
who wants one will be able to get one soon.
