Channel 9 has published "The Best XNA Movie in the UNIVERSE" ... or at least they claim they have ... ;)
... well, anyway, the video covers the official XNA launch event, so you'll find interesting interviews with the guys we can thank for bringing to life this baby named "XNA GSE" as well as some community members that attended the meeting.
On GameTrailers.com you'll also find a video new covering XNA GSE -in line with previous videos available on this regard at GT's site- with more interesting interviews: XNA - Part 1. This video can be also found on YouTube with some other XNA-related videos.
