3D Buzz, authors of many previous outstanding Unreal Ed video tutorials (including those bundled with various versions of UT 2004) are apparently at work on supporting videos for the Unreal Development Kit. Jason Busby mentions in a forum post (thanks Converged):
I can assure you... VTMs are coming. We had over 13 hours complete... and then had to re-record everything because of a few things in the UI that got moved around or changed at the last minute. Fun fun.
In any case, I don't think you guys will have to wait much longer than a week.
