Lemme give this prediction thing a try:
WWE Universal Title Match
Brock Lesnar vs. Bill Goldberg
Lesnar obviously. Goldberg said on Twitter he's taking time off.
WWE Title Match
Randy Orton vs. Bray Wyatt
Probably the hardest match to predict. I believe Bray retains but will drop it to Orton somewhere down the road.
Fatal 4 Way Elimination Match for the RAW Women's Title
Nia Jax vs. Sasha Banks vs. Charlotte Flair vs. Bayley
Banks heel turn happens here and costs Bayley the title to become the NEW Women's champion.
WWE United States Title Match
Kevin Owens vs. Chris Jericho
Kevin Owens, due to Y2J's upcoming tours away from WWE.
WWE Intercontinental Title Match
Baron Corbin vs. Dean Ambrose
Corbin wins and becomes the new Intercontinental champion to move his push along even further, sort of a test run with the title.
Triple Threat Ladder Match for the RAW Tag Team Titles
Enzo Amore & Big Cass vs. Sheamus & Cesaro vs. Luke Gallows & Karl Anderson
Enzo/Cass win the titles here and get their big WM moment.
Six-Pack Challenge for the SmackDown Women's Title
Naomi vs. Mickie James vs. Carmella vs. Natalya vs. Becky Lynch vs. Alexa Bliss
With this being in Naomi's hometown, I believe she becomes the new SD Women's champion.
Non-Sanctioned Match
Triple H vs. Seth Rollins
This feud won't end here and expect a Samoa Joe run in. Triple H with the win (His WM record goes win-lose-win back and forth and he lost last year), expect Seth to pick up the win against The Game down the road.
Roman Reigns vs. The Undertaker
As much as I hate this match, it's a clear cut that Roman wins and puts The Deadman down to further establish his Vince McMahon Erection Tour.
John Cena and Nikki Bella vs. The Miz and Maryse
Special Guest Ring Announcer: Al Roker
With Cena and Nikki taking time off and possibly Nikki's last match in the WWE, expect them to win this as a sort of final thank you for Nikki. Hopefully it doesn't derail Miz/Maryse long, they are gold.
Shane McMahon vs. AJ Styles
The only option here is a Styles win, let's just hope he can pull a good match out of Shane.
Kickoff Pre-show: WWE Cruiserweight Title Match
Austin Aries vs. Neville
Neville retains, expect the feud to continue past WM.
Kickoff Pre-show: Andre the Giant Memorial Battle Royal
Sami Zayn, Braun Strowman, Goldust, R-Truth, Curtis Axel, Dolph Ziggler, Jey Uso, Jimmy Uso, Chad Gable, Jason Jordan, Primo, Epico, Bo Dallas, Jinder Mahal, Rhyno, Heath Slater, Apollo Crews, Mojo Rawley, Big Show, Curt Hawkins, Tyler Breeze, Fandango, Tian Bing, Mark Henry, Killian Dain
I could see Big Show winning it but gotta go with Braun here to pick up his momentum as The Monster Among Men.
