From the translation:
Interviewer: Congratulations on completing Bloodborne! How are you really feeling about it now?
Miyazaki: I’m 30 percent looking forward to the players enjoying the game. The remaining 70 percent is freaking out. (laughs) It’s always like this. It hasn’t changed. This is the roughest period. (laughs) It’s scary…like you don’t know what’s going to happen. Development finished, before it goes on sale… this period makes me so uneasy, I just can’t stand it. Before it’s finished, there are still things you can do. Once it’s released, you can deal with problems that arise. Right now, there’s nothing I can do. So, my feelings now are a mix of hoping the game is enjoyed and a vague sense of fear. That’s how it is, honestly. I’d like to be brimming with confidence, but you have to prepare yourself mentally.
