Even though Im not the guy running the site, I can tell you this: There are no tracking firms for Europe, to my knowledge. UK has some, but outside of them, I haven't seen any rock-hard data from any other country. Once in awhile, the manufacturers release data about various regions (IE, MS talking about the 100k units of the 360 being sold in Austrailia, a record).
BTW, if the admin reads this, PLEASE GET THE SEPTEMBER NPD DATA UP! I wanna see how the top games did!
1) Xbox sales will soon be added to the console shipments page, as well as a 'go back in time' feature were you can look at data from any period over the last 15 years and see how many of each console had been sold then
2) We will be having European data in the new year - stay tuned !!
