“I have only my personal theory to that situation. I left first party so I don’t know what’s going on, but my theory is, you know because I remember, you know, Miyazaki San really really loved Bloodborne, you know, what he created. So I think he is interested, but he’s so successful and he’s so busy, so he doesn’t want, he cannot do himself, but he does not want anyone else to touch it. So that’s my theory. And PlayStation team respect his wish. So that’s my guess, theory. I am not revealing any secret information, just to be clear.”
