This news, it can be seen as Japan being not the main market/ advance as it was for this current generation (and if it was). In this case the reason can be a bit different but less or more, there are more title than previous years being first release/created outside Japan (...just my feeling)
There are others majors games even not release in Japan (Dead Space 2 for ps3, Virtua Tennis on Wii irrc)
Lot of time i saw comments as JRPG are now out of fashion, not good etc... Japan don t create any more good games but that is wrong. It s more others country/company are doing also well and US market being the most important (as it was be long time ago).
And there are still a lot of really good Japanese games (and JRPG), ask
about some recent titles fixed...
Also one other aspect is worldwide distributions in electronic goods, now only really specifics products will be release before in Japan.
is right, Xbox360 in Japan...
it s like Japanese motorbike in motorbike gang in US (forgot the exact term, i watched too much the drama, Sons of Anarchy, with Charlie Hunnam)
