Hm, Sony should be moving up to 15 million sellers in just a month or so. God of War will cross a million its very first week in all probability, and Ratchet & Clank Future: A Crack in Time, Heavy Rain, and the God of War Collection should all break a million within a month or two (assuming I'm recalling correctly that the Collection will be hitting Europe very soon).
Socom: Confrontation will also finally break a million in a few months, putting them at 16. As will MAG. Of course, Confrontation has easily made up that last 15k in digital sales, I'm sure. :P
