I would wait until theres some word on whether or not stuff is edited and whether not its censored like the PPV was. Personally, the only way I would think about buying the DVD is if it wasnt censored and the left everything in tact (which I know they wont, but to what degree will they mess with the chants/music/etc is what Im going at)
I have the PPV stuck on my Hard drive right now, as I was stupid and didnt change the quality of the recording to 2.5 hour mode and I cant fit the whole thing on a DVD.
