Not only hasn't Benoit been featured, but didn't they even massacre-edit a match on the Austin DVD where he showed up? Some match that was Austin/HHH, I think.
As already mentioned, that's the difference with Savage... sure, they didn't edit him out of the full PPV DVDs, but the IC one was the first (almost ever, I think) where they specifically featured a Savage match by choice. That's a huge change from the fingers-in-ears 'la-la-la-la-la-can't hear you-la-la-la-la' stance that Vince has had since the 90s. It's sort of sad that the closest comparison to the Savage thing is a guy who murdered his own wife and child... hell, it was mocking, but even Warrior got a DVD. Really, though, up until the IC DVD, the only two people that apparently never existed were Savage and Benoit.
The Orton DVD is a ways off, I'd imagine. Hell, Edge only JUST got one, and he's been in the company for almost a decade. Will be interesting, though, and Benoit may actually mean we don't get a retrospective DVD for a *long* time.
Sidenote: recently got around to watching the Four Horsemen DVD. Yikes. It was right around when they had an interview where they called Benoit a 'monster', followed by a shot of him and Nancy. Uncomfortable.
EDIT- starting typing *before* Busta posted. Don't know how 24/7 handles it, but I *think* I remember hearing that Benoit was initially edited out of Nitro and whatnot. It may have changed as time has passed, though.
