So in theory we're going to get the following if you believe a combination of rumours and WWE logic:

Universal Title: Lesnar (C) vs. Reigns
WWE Title: Styles (C) vs. Nakamura
Undertaker vs. Cena
Rousey & Strowman (or Rock) vs. Steph & HHH
SD Women's Title: Charlotte (C) vs. Asuka
RAW Women's Title: Alexa Bliss (C) vs. Nia Jax AND/OR Sasha Banks (C) vs. Bayley
RAW Tag Team Titles: The Bar (C) vs. Bray Wyatt & Woken Matt
IC Title: Miz (C) vs. Balor (or Strowman)
Rollins vs. Angle
Zayn vs. Owens OR The Usos (C) vs. Zayn & Owens OR Something featuring Shane vs. either/or both Zayn & Owens
Finals of the Cruiserweight Championship Tournament
A Women's Match on the Pre-Show
5th Annual ARMBR

Is there anything I'm missing here, or are we more or less there with this?
