I have one question: I've been following the weekly US hardware sales and seems like 360 is selling about 50,000 consoles on average (weekly) yet the the total world wide sales are constant. Can someone explain how the sales are extrapolated and adjusted?  Is it done weekly, monthly...?

No they've been rising, you just have to understand that NA is where most of the Xbox's are sold, Japanese and European sales of the 360 are not that big, which is why its a slow movement

Not only that, I dont think European numbers are adjusted as regularly for the 360. Wii sales are consistent (always sold out), whereas the 360 sales can change.

it does seem that the "others" value keeps getting scaled back in order to prevent the 360 from hitting 10 million... Everytime the american data goes up the "others" goes backward the same amount.

prevent, lol, you're funny.

you actually think ioi is doing something like this, on purpose?

well... could it really be tracked? I mean, "others" has gone down in 150k in the past week. There is no real official values put out for "others" just an arbitrary figure that supposed to include australia, europe, china, india, new zealand, south-america, south africa, indo-asia, korea, and i'm guessing canada and mexico (now that the american data seems to only represent USA) That's a lot of data that is rolled into one big value. Without any kind of tracking as to why it fluctuates it could be arbitrary. The 360 data went up to about 9.8 after the latest data was put in and then dropped down to below what it was before the week started.

 wrong, america does include canada.

i think the numbers are pretty reasonable tho, and you know, once we get official numbers, ioi can change it you know, it's not like this is the end of the world or something, 'others' is still pretty much of a guess
