Marantz has put out a video showing off some of the features included in the Marantz PMD620. There's not much here that we didn't already know, and for some unfathomable reason, there are no closeup shots of the recorder in action. But I supposed Marantz is known for making audio gear, not for making high quality videos.
You do get a sense of just how small the PMD620 is when you hold it in your hand though.
