The Wii and DS were really dominating in Japan until now. Recently the PS3 has gained quite a bit of steam for Japan, Japanese developers/publishers will need some time to adjust to this, but I think we will see more and better efforts in the future (the 360 can also indirectly benefit from this as it's a non-factor for Japan).
In general I find it funny western gamers think western developers are better. If you ask a Japanese gamer, he would probably come to another conclusion.
