So if GT5 dropped by 61% this week in UK that means 39% of 265k which if my maths is right is 103k. Which is still pretty good.
If UK was the top selling country for GT5 in EMEAA as looks likely and we apply that drop to last weeks numbers would be a 2nd week for EMEAA of 457k. Which is 85k down on GT4's 2nd week in the region. But of course that is if the drop is the same for the other countries too. If it did do 457k that is pretty awesome. To put that into context it would of beaten MW2 and Black Ops' 2nd week on PS3 in EMEAA. Of course it could end up being lower then that though.
