You've got four games to review, merchandise, tons of people you could interview, tons of abandoned games (or are they) to discuss, the art book to go over, HD remakes, plus other new stuff on the horizon.

You say there is nothing to talk about, and yet, this forum is full of people talking about stuff. Podcasts don't have to be just news reports.
