"For me, the whole departure from Sony was not exactly the ideal route that I wanted to go, but in the end I think it is the absolute best thing I could have ever done. I am not going to go into any specifics as to what it is I am working on now, which sucks, but I can say that I am cooking up several things.
I know for the God of War fans out there it might be a bummer that I am not working on God of War 3 (or for some it may be a good thing I am not) but rest assured that it is all in good hands. The Sony Santa Monica team is one of the best teams I have ever worked with. Also, immediately after I finished God of War 2 I was already working on the story and design for the third game. So when Sony and I finally did part ways the foundation of the game, along with story that completes the arc we began in God of War , was complete. I wish I could have been there to see it through to the end, but it was just not meant to be I guess. The story is going to finish off with a very big, very epic bang though. I think everyone will be quite pleased. Well, everyone except edge magazine that is. :)"
