Bear in mind that a lot of those PS2s were probably used mostly to play DVDs. The PS2 was the cheapest DVD player in common circulation for a while. Some PS2 owners got 360s instead because they just wanted their Maddens and Grand Theft Auto 4 for the lowest price possible back when the PS3 was $599. Some of them probably refused to get a system without Gran Turismo; The Gran Turismo games sold over 28 million units on the PS2 alone. JRPG fans that helped bolster the system (FFX sold less copies than only the GT and GTA games) have largely migrated to the handhelds, the new home of the JRPG, or have simply given up on the genre in favor of WRPGs like Fable and Mass Effect and MMORPGs like World of Warcraft. The often overlooked casual PS2 gamer, who played movie tie ins, Guitar Hero, and the various Sony-brand 3D platformers, has naturally gone over to the Wii. Some of them got their PS2s in 07 or 08, at which point the system was still competing with the PS3, and are unwilling to upgrade after two or three years.
How's that for a concise response?
