Didnt read the whole thread because its become quite lengthy, but thought before even seeing this thread was why not a standard PPV just like you see with boxing and wrestling. If youre going to offer a broadcast, why limit it to a crappy webcast...put it on real television. Better quality broadcast and you can charge more ($50 maybe?). Not like people arent going to invite their friends over to make it cheaper, and $50 is enough that DCI would make money off of it.
Another possibility: do the webcast, but make it only available to those who have preordered DVDs. Then more people will preorder the DVDs and pay the early price rather than waiting to get it half off the next summer.
Off topic I know, but...if the corps are making royalties off the DVDs/CDs, wouldnt it be helpful if DCI actually made all of these products available? It looks like they basically get a couple of batches made, and when that runs out, they are gone forever. For example, in their online store, you can no longer purchase CDs from 2000, 2004, 2005, 2007, or anything before 1999. Why?
