Sony says that the 14 million active PSN accounts does indeed combine figures of PSP and PS3 owners. This concession was carried with the confident assertion that one person using the same login for both is still treated as a single account.
"Seeing as PSP does include PSN services, yes those numbers do include all PlayStation Network registrations," a Sony spokesperson explained to GameSpot. As with the Xbox Live statistics, the figure includes multiple accounts used on the same console, the spokesperson added.
Though the company has clarified its position, it is still unknown how many PSN users are logging on via the PS3. Edge has contacted Sony regarding this matter.
