Fez's dev to Japanese dev At GDC: "Your games just suck"...Japanese Developer Leaves GDC

[Barozi]

Nintendo is simply excluded because they managed to keep the quality. Same is true (to a slightly lesser extent) for Capcom. But then ?
Some very popular and critically acclaimed Japanese gaming series are dying in case of sales, quality or even both.

Pro Evolution Soccer
Final Fantasy
Kingdom Hearts
Tekken
Soul Calibur
Dragon Ball Z fighting games

Well you get the idea.
