Well not really. Austin/Punk can go down bad too. That sort of thing as much as fans like me would want to watch, there is a whole wider audience for WWE to cater which includes kids and other not so high on rebel characters.
Rock/Cena was a draw because Rock had his fans from previous years- us, the new kids from the Disney movies and who not. Cena being the kid drawer and well, drew us to see get his ass whooped (which didn't happen though) from the Great One. It can be easily visualized to be a big big draw for WWE.
Austin/Punk needs to be played out well and frankly, I would even go ahead and say that it wouldn't help Punk much in his move to the top.
