Heres what I think the match order could be with some predictions;

Pre Show: Tag Team Championship/ Cesaro & Kidd vs The Usos (Nattie and Naomi get involved, the titles either change hands of it becomes a mixed tag.)

Show Open, National Anthem, followed by the Intercontinental Invitational/ BNB, Bryan, Ambrose, Ziggler, Harper, Truth, Stardust, and...JBL? (Bryan/Ambrose Faceoff and Huge Pop, Dolph sells like a Champ, JBL enters from announce table, ultimately Bryan goes over to start the show hot unless... Sheamus returns and Brogue Kicks everybody and wins the belt. Fuck.)

U.S. Title: Cena vs Rusev. (Rusev Wins, no way Cena carries a secondary title. Cena wonders if he lost his mojo and the big russian winning makes the crowd want death, so next is....)

Undertaker vs Bray Wyatt. (Excellent spooky entrances, Taker wins, it's the long goodbye. Wyatt morphs more into David Koresh and Jim Jones afterwards.)

The Andre the Giant Memorial Battle Royal: (If Sheamus doesn't return in the I-C Match, he will here and win. If not, Axelmania runs wild. Hulk Hogan gets a paycheck and shows up. Real American Ensues.)

Triple H vs Sting. (No way Sting loses his first WWE match killing all of his drawing power. Sting wins, it's whats best for future business.)

Shitty Kevin Dunn Flo-Rida type dance music Video Package. Wrestlemania Axxess Highlights, Tonight's Attendance, Hall of Fame inductees.

Orton vs Rollins: (Rollins will do what he does and it will be awesome as fuck and this one should be a crowd pleaser Orton wins though, he's returning and needs momentum besides Rollins has bigger fish to fry, to help HHH save face either on Raw the next night or when the Authority seems deteriorated the next month or two. )

A.J. & Paige vs The Bellas (The Comedown Match to get people to get up for Lesnar & Reigns, The Bellas win but get some kind of comeuppance so that A.J. and Paige stand tall and get to leave with the Music. )

WWE Championship: Brock vs Roman (I want Brock to win but Reigns is going to get the rub from defeating the Beast who defeated the streak. Michael Cole will holler "Roman Reigns, Roman Reigns" and Reigns will pose with the championship when they sign off. R-Truth will mock us at the end. Wishful Thinking: If they want a WrestleMania Moment, this is where you turn Cena. Have him pass the torch to Roman then clobber the fuck out of him. It would take the sting off of losing Lesnar and would be the way you sell Roman to the masses, while getting Network buys and a good rating for Raw the next night. I forget though, Cena sells T-Shirts. R-Truth it is.)
