Forums - General Discussion - Europe Pre-order Chart?

first of all i want really thank all the team around vgchartz about the big work the put into this site, it's really amazing. i know that is really hard work to do this. one what i really like are the pre-order charts for japan and us, as it gives an idea how good a game could sell before release...my question is now why there don't exit one for europe? isn't there enough demand or it's because getting numbers from europe it's complicated...?
