The two participants in the main event of WrestleMania 29, and the title they will be fighting over, appears to have been leaked online.

Apparently the details of the bout were released as part of a memo (leaked by WWEDVDNews.com) to retailers and DVD companies who will be selling the Royal Rumble 2013 DVD. In the memo, it coaches the would-be retailers on key selling points, giving a statistic about last year's Rumble DVD and a revealing tidbit about WrestleMania.

While plans can change at any moment, the memo certainly seems to suggest, rather strongly, that the main event will be The Rock vs. John Cena for the WWE championship. 

This should come as no surprise.

The Rock is a major star outside the WWE. Having him come back for three pay-per-views wouldn’t make much sense if he weren’t going to be the man to beat for the WWE championship.

Given the massive financial success of last year’s WrestleMania, which also featured Rock vs. Cena, it seems the WWE is trying to capture the magic once again.

It could be a huge gamble trying to repeat the success of WrestleMania 28. But think about Triple H vs. The Undertaker two years in a row. The match was kept fresh by adding in Shawn Michaels as the guest referee.

Perhaps having the WWE’s biggest prize on the line will be all that is needed to have this one break records as well.
