Its more like 2007 is the year of the huge game....Regardless of system. Each system has a few 1m+ sellers. X360 has Mass Effect, H3, GTAIV Wii has SSBM, SMG, ect DS has Pokemon D/P PSP has a few games you listed PS3 has MGS4, KillZone2 and GTAIV Easily the biggest year in gaming history for all the systems. Hopefully consumers have enough cash for all the must-have titles.
Back from the dead, I'm afraid.
