Quality wise, I don't think it will. Quantity wise, Rock-Cena will surpass this not only because it's on Mania. Not only because the match will take place on Mania, but also due to the fact that Rock is a household name, one that every wrestling fan and most non-wrestling fans know. The match is one of the very dream matches left and ,arguably, the biggest match left that wrestling fans want to see.
Comparing the two is an unfair comparison either way. They are completely different angles, and even if Rock-Cena doesn't live up to the hype of this match, in hindsight it won't affect the anticipation when it comes to the match. Around Mania time people will not be saying "Man, this feud is completely underwhelming and very inferior compared to the unparalleled feud of Punk and Cena IN JULY; instead they will be saying "Man, I cannot wait for Rock and Cena. It's going to be epic."
