I think this is a very good number consediring that next week , we will have numbers for the rest of PAL region (France, Germany, Spain, Italy...and Australia).
(This game is released on 13th in UK and 19th in rest of Europe)
I hope it might sold 60K first Week in europe and 60K more for NA.
And perhaps 1Million LTD, as Shaun White. Who knows ?
