So called 'PS2 upgrader' - SOCOM: Confrontation. Not a massive seller like Gears or MGS4, but a VERY loyal fanbase. People are still playing SOCOM online on their PS2's. A lot of people will 'upgrade' to PS3 when SOCOM PS3 comes out.
Tekken 6 is also a 'PS2 upgrader', but it isn't such a big deal.
The 360 has nothing compared to last year. Halo 3 came out and still the 360 couldn't outsell the PS3 that holiday season worldwide. All the PS3 had last year was Uncharted, a new IP, and Ratchet and Clank.
LittleBigPlanet is the biggest game this holiday season in terms of 'upgrading' PS2 owners. Just watch it happen
