This is by no means an official or confirmed match card, and as per usual, plans are changing on a weekly basis.
WWE World Heavyweight Championship
Brock Lesnar (c) vs. Roman Reigns
-Rusev vs. John Cena
-Triple H vs. Sting
–Bray Wyatt vs. The Undertaker
-Seth Rollins vs. Randy Orton
–Daniel Bryan vs. Dolph Ziggler
-Andre the Giant Memorial Battle Royal
-Goldust vs. Stardust
-The Miz vs. Damien Mizdow
WWE Tag Team Championship
The Usos (c) vs. The Ascension
Intercontinental Championship
Bad News Barrett (c) vs. Dean Ambrose
Obviously one or more of these matches would take place on the WWE Network pre-show. Nothing here is out of the ordinary. I would be surprised if both the tag team splits took place at WrestleMania. Look for Goldust vs. Stardust, as the elder is looking to wind down his full-time career, and they can always use Miz and Mizdow in the Battle Royal.
As we have been reporting, WWE is at this point still unsure if the Undertaker can perform at WrestleMania this year, although they are moving forward with Bray Wyatt as if the match is a lock.
