games don't have to be million sellers to be considered successful . There are lots of games on PS3 in japan that sold a lot and brought profit like- DMC4, MGS4, Yakuza, RE5, VC, and even niche games like Demon's Souls and Disgaea are successful.
all million sellers on wii are first party titles, third party title don't get nearly as much success
its hard to say we have a crash when we have a console selling 2m in ONE MONTH and lots of games selling millions (Gears, Fable etc) seriously some developers are closing yes but that have more to do with their recent failure than current economy. Good games are still selling as much as they used to in the past.
