I just got a PM from Phanman asking about the PAX 2007 DVD and figured I'd just answer it here, since he's probably not the only one wondering what is up with it.
There are three main components to the DVD - the "documentary" portion, the Keynote / Gabe/Tycho Panels and the Concerts. The "documentary" portion was done by Rocco and the guys at Mega 64, and to be honest I've had the final version in hand for months... he did an amazing job with it. The Gabe/Tycho Panels and the Concerts are being edited and the audio is being mixed. I wish i could make the process faster, but there's a lot of back and forth so it takes a lot of time.
Expected release date? Man, I'd love for it to hit the PA Store in the Spring. Maybe earlier.
