Pretty much . Vgchartz has no way of tracking games sold through the playstation network , this has been an ongoing problem for PS3 games also like Socom , Burnout which have full retail versions availible for digital download.
This is especialy problematic when comparing across platforms (PS3 vs 360,Wii & PSP vs DS) because IIRC Sony is the only one out of the 3 which sell full retail games on their store.
