It would be fun to hear about the people who are making the game, like level designers and artists. Hearing Todd Howard drone on and on about how he used to be ridiculed for developing games and how he's now a gaming bigshot isn't very interesting.

True though, the sound designer was very interesting, and there are more I'm sure. It'd be real interesting to hear from the guy in charge of the improved AI
