Why not Syles Vs Owens Champ Vs Champ? They kinda have been playing that up lately with their mini twitter war. With all the PTers coming in for the RR and Mania keeping the titles on those two shouldn't be a problem.
You don't have Balor on there and they are pretty high on him especially seeing how he was originally the champ and if not for injury he would probably be a few months into his reign.
they're not doing champ vs. champ with no title on the line at Wrestlemania lol. It'll probably be Balor if he's healthy against Owens. It seems like Taker/Styles may be a go unless Vince changes his mind.
Taker/Styles
Lesnar/Goldberg III
Rollins/HHH
Cena/Ambrose
Owens/Balor or Jericho
Orton/Wyatt
Strowman/Reigns (US Title)
Show/Shaq
Charlotte/Bayley/Sasha
Becky/Nikki
IC Title
SD Tag Titles
Raw Tag Titles
Andre Battle Royal
everything from Show/Shaq and upwards is what I'm pretty confident in with maybe a few pieces changing (Cena/Taker, for example, Styles against some other top name, Ambrose vs. a Raw guy). Everything else below it is pretty much guessing/logical.
I'd hope The Revival is on Smackdown and the SD Tag Title match can be The Revival vs. American Alpha vs. The Usos. For the IC Title continue the pattern of the past two years and have a multi-man ladder match with The Miz, Ziggler, Corbin, Kalisto and one of Zayn/Cesaro if they get moved to Smackdown.
