I think the difference is one of quality.
For most other cons, BBF creates a "best of" video cut within a few weeks. For some reason EF decided that we'll release con DVD's instead, which require a lot more work, not just on the video part. The entire audio of all the shows and dances will get remastered and redone, all videos get scanned more, there's more video tapes to begin with, and then there's DVD authoring to be done.
If EF would decide to just release a con video in the same style as every other BBF video, I am sure he'd have one released a month or two after EF. But, as it stands now, the decision to go for quality and DVD is what is holding the whole thing back, I think.
Personally..... I think I'd rather have a con video that's actually happening than a full-bells-and-whistles con DVD that may either never appear, or appear with a delay of multiple years.
But, anyway, that's nothing to do with sponsor goodies, so if you want to discuss further, let's open a new thread for that.
Best regards,
Fairlight!
