Wrestlemania 31 is going to take place at the Levi's Stadium in the San Francisco Bay Area, California on March 29th.  There will be many events taking place at WWE's big event, and here are some predictions of what will happen at WrestleMania 31, as well as a guide of how to watch online. 

There is the main event, with everyone wondering if the defending champion Brock Lesnar is going to hold his title and defeat the 2015 Royal Rumble winner Roman Reigns.  The International Business Times says that Reigns is ready to face Lesnar and he "matches up well" with the WWE world heavyweight champion. This will be Reigns third time at Wrestlemania but first time as a singles star. 

There is also going to be an interesting story this year about The Miz and his former stunt double, Damien Mizdow.  It is possible that Mizdow will win the Andre the Giant Memorial Battle Royal against the Miz, and put an interesting twist on their estranged relationship.  Also to appear in the Andre the Giant Memorial Battle Royal will be Curtis Axel and Ryback. 

There will be a Ladder Match between seven superstars of wrestling that include Bad News Barrett vs. R-Truth vs. Dean Ambrose vs. Luke Harper vs. Dolph Ziggler vs. Stardust vs. Daniel Bryan.  Heavy.com predicts that the three men that will reign supreme in the match will be Daniel Bryan, Dolph Ziggler, and Dean Ambrose. 

As far as the women's event is concerned, it will be AJ Lee and Paige vs. The Bella Twins, Brie and Nikki Bella.  It will be interesting to see who wins with these rivals, and I'm not even going to attempt a prediction here. 

One of the biggest anticipated events at WrestleMania 31 is that Sting and The Undertaker will finally be put on the same card.  This would be the first time that these legends would ever come face to face, but this event might not take place until Wrestlemania 32, according to Bleacher Report.

Then there is the big battle between John Cena vs. Rusev.  At Fastlane 2015, Rusev made Cena pass out, and it is possible that Cena will make some kind of comeback against the massive Rusev.  Considering that John Cena is probably the biggest spokesman that the WWE has, it would be a safe bet for him to win this match.
