What KingCal said. It's all about the money as Vince would say.
Undertaker's a legend and they know they can make lots of money of him. 20-0 is a perfect landmark to release a DVD and if The Undertaker goes another few years expect another DVD to come out. Maybe he could go to 25-0. The Rock had a DVD last year and he'll be getting a new one soon to include his match with Cena at WrestleMania and maybe the match he wrestles in at WrestleMania 29. These big names like Undertaker and The Rock have HUGE fanbases and people will buy them regardless if they've seen most of the matches before.
Just checked on wweshop and its PG rated.. Would that probably mean the blood, hanging etc is edited out or something? I fucking hope not, if so then thats ridiculous.
Well, that's really ridiculous. I guess they'll change the screen to black and white every time the camera closes in on a bloody face. That's stupid IMO. With that said, how many of Taker's WM matches have blood in them? Only ones I can think of are against Boss Man and Flair. Edge is also busted open at the end of the WM24 match but it's no big deal.
