I really have no idea what plans for most of WM are or even could be at this point
Brock vs Seth
Ronda vs Charlotte vs Becky
Probably Miz vs Shane
Other than that? Who fucking knows. Almost all of the upper card guys seem to have no angles a month and a half out. AJ has feuded with every top guy on SD, extensively, lost multiple matches to the champ since November. Joe is always booked like a killer but always loses and decisively lost every feud, plus he's a heel and so is most of SD's crew. Orton is Orton and who gives a shit. Nakamura looks destined for the pre-show this year either in the battle royal or in an apparently unlikely duo team with Rusev against the Usos maybe? The fuck is Jeff Hardy up to? Rey vs Almas seemed like a lock but then they ran it on TV 5 weeks in a row. Neither of them were even mentioned on the PPV.
Then you go to Raw and....shit, it's even more of a mystery over there. Can they really do Braun vs Corbin bullshit AGAIN? No one gives a shit about that feud, at all, they've repeatedly added and subtracted Drew and Lashley whenever it was convenient but no one gives a shit about any involved and it has massively lowered Braun's stock. I'd expect basically the whole mid card of Raw in some kind of gimmick match for the IC title. But then what about the Revival? What about The Bar? Asuka and the SD Women's title? Buddy Murphy has run through the entire cruiserweight division twice over now. Did you know R Truth is the US Champion?

Now there's the women's tag titles so I'd imagine that will be another excuse to have a big scramble tag instead of two battle royals.
It sucks that Ali got hurt and taken out of the EC, but fuck it, they should run with Kofi vs Bryan at WM and have Kofi win the belt. They have something, crowds will be 100% into it, Kofi deserves his moment. If I'm not mistaken that was his first WWE Championship match and he's been with the company for 11 years.
