Here is what was actually said in the interview:
Journo: "What frame rate and resolution are you targeting?"
Translator: "Resolution and framerate... have you decided these yet?"
Yamagiwa: "The resolution is going to be 1080p. As for the frame rate, well, stretching it to 60, with how this game is.. Demon's couldn't do it either, well I guess we probably won't be able to make it up to 60... It sounds like I'm making excuses but, anyway we're targeting 1080p 30fps.
Translator: "First of all it's going to be ..." (makes up a bunch of shit that Yamigawa didn't actually say, talking about action games being best at 30fps)
Yamigawa (interrupting): "well it's not ... I mean no matter how I say it, it's going to come out like an excuse I'm afraid"
Translator: "well, from the first they are not targeting 60fps because ..." (more conjecture)
