You guys know Iwata Asks. They're a pretty cool series of interviews.

This is another entry in that series, only the interviewer is Shigesato Itoi, best known in the west as the creator of EarthBound. He's interviewing Miyamoto about his design philosophies and also about Super Mario Bros. specifically.
These two are my favorite developer personalities, and the interview so far is really interesting. The tone is very different from the normal Iwata Asks - less formal, more laid back, and (it could be argued) more interesting.
