Well the point is, people can say whatever they want, but as DragonSlayr81 mentioned, Konami may have "invited" him to leave. I'm not trying to stir up a rumour but Japanese society is not one where being fired or asked to leave is a nice thing to share with the public. Thousands of fans know your games and your face, you're surely not gonna say "Hey guys I got fired" or "Hey guys Konami basically forced me to leave". "Hey guys I decided to leave to make games the way I want to" sounds a lot better. Plus, the fact that the guy is all over US now, where most of his fans are. Why not stay in Japan? I bet because no one gives a poop about him over there.
