Maybe Sony just stopped caring to cater to the Japanese because the Japanese seemed to stop caring for them
To start rolling the ball I think you need an huge established franchise (like GTA or whatever) or some new IP that has such huge appeal that it can singlehandidly move systems like crazy (Wii Sports, Brain Training, Nintendogs whatever).

And LBP is neither of those 2 options. Maybe it'll be like that PSP game LocoRoco?
But I don't agree on Home. Just minutes ago "Second Life" was discussed in THE NEWS in the Netherlands. This does not happen often unless it's making it's mark on the Dutch market (same for Brain Training but I can't remember any other games). For those of you don't know it, it kinda is like Home as the title suggets, a digital life, but a lot crappier (from what I've seen, haven't played it because I don't care about it). If Sony doesn't **** it up it *could* be to PS3 what Mii's are to Wii (thus kind of huge / appeal / selling feature (what's that word for that again?)).
