 http://www.accessgames-blog.com/rsp_dblog/2010/06/deadly-premonit.html It's all in Japanese, except the questions. I gave Google translate a go and it seems somewhat understandable.

If someone can translate it better, I think we'd have an easier time with the interview. Here's an excerpt of his favorite games:

I think I can translate this.  However, I'll have to do it in several stages, because I'm at work and don't have much time, right now. So, here are the first two answers, for now. I'll edit and add the rest later. I didn't keep the translations too close to the original Japanese. I wanted the translation to feel natural, not too stiff.
 
"Deadly Premonition is very ambitious, what made you not want to make just a normal survival horror game?"

At first, we wanted to make more of a mystery game, its horror aspect being almost non-existent.
 
Since the original idea was to have a scientifically investigating protagonist, we aimed for something much more urban and cynical.
However, as we went along implementing these ideas, and meeting upon meeting of the producer and other members of the staff had occurred, we changed things up, and the game ended up having the strong occult slant you find in it now.

You could say, we completely abandoned the route we originally had set foot on, as to the game's content and direction. 

Thinking back to it now, the invention of the "coffee oracle" and "Zach's existence" was what set and established the game's character.

While its return appearances play quite a big role in the game, the sign's meaning can change dramatically, depending on the particular viewpoint of a character.
A thing of tremendous importance, a divine symbol, a simple drawing, or -- if we were to believe Harry -- it might be a harbinger of what is to come. Who knows?

I think this interview was originally in English, and then it was translated to Japanese. Here is a link to the English interview:
