In Episode 50 of the Engadget podcast (I've listened to them all so far!), Ryan and Peter announced (sort of) that they will eventually do a video podcast once they get the time and equipment to do it right.

Combine this with the recent announcement of the Engadget Lab, and I can't wait to see a?video of Ryan and Peter walking around in white lab coats with all kinds of bubbling concoctions in the background!
