I think we can assume that X360/PS3 versions of Fifa dropped around 50% and sold around 100k each this week (bringing the totals to around 300k each). Even if PSP/Wii version dropped less (and they probably did) that doesn't matter much as they represented at most 6% of last week' sales.
Expect both X360 and PS3 version of Fifa 09 to achive Platinium awards in October ELSPA update. PS2 version will probably get the Silver award.
