Here I went that other topic, and pulled out the worldwide sales, which is what I think you intended to post.
January Hardware Sales
PS2: 448,000 (-84% over December sales)
XBOX: 164,000 (-84%)
GCN: 81,000 (-87%)
GBA: 266,000 (-88%)
I wouldn't suggest you edit you post though, unless you changed the title, cuz I don't think gc fans would consider that very uplifting.
Wait a minute something is fishy now that I compare the two. The first artical you posted said PS2 push 2.5 million units in one month! Are you sure those numbers arn't consoles shipped? Not sold?
