I believe the matches that are included in the main part of the DVD will be clipped, similar to how WWE does the "From The Vault" segment on Confidential. The matches in the extras will be shown in their entirety. I could be wrong, but that's what I've heard.
I believe the Michaels vs. Jannetty match was an IC title match from 1993. Everyone else feel free to correct me, but I believe this was the blowoff of their feud with the cage introduced because Diesel (who had just debuted) had cost Jannetty the title previously.
Sure looks like they could easily angle for a Miz/Morrison vs. Jesse Festus vs. Dreamer/Delaney, except that giving Colin Delaney a WrestleMania payoff doesn't sound like something our favourite company might do.
