Brock Lesnar vs Seth Rollins (WWE Universal Title Match)
Already confirmed - would love to see Seth getting the title back from Part Time Brock, but don't see that happening any time soon.
Kofi Kingston vs Randy Orton (WWE Championship Match)
Not sure who else there is for Kingston to beat - could easily use their past history to build up to this match.
Shane McMahon vs Kevin Owens (for control of SmackDown)
Could be a fun match and with the stipulation in there, makes it believeable for KO to try and run the show.
Bayley vs Ember Moon (SmackDown Women's Championship)
Already confirmed - giving Ember a title run could be fun, her work in NXT was top notch and deserves to show what she can do with the spotmoonlight on her.
Becky Lynch vs Natalya (Raw Women's Championship)
Already confirmed - seems to be an odd choice for Natalya, plenty of other talent could put on a decent match with Lynch.
The Iicnoics vs Kabuki Warriors (Women's Tag Title Match)
I was going to make this a triple threat match with Bliss and Cross being involved, but that would then be 3 triple threat matches on the same card, plus by the time SummerSlam comes along, they might be having a match of their own.
The New Day (Big E and Xavier Woods) vs The Club (SmackDown Tag Title Match)
I can see The Club becoming dominant (and probably expanding) as time goes by. Even if they weren't to win the Tag Titles here, a strong showing against arguably the best Tag Team in WWE at the moment would go a long way.
Revival vs Usos vs Heavy Machinery (Raw Tag Title Match)
Revival and Usos are already established tag teams on Raw and Heavy Machinery need to be included in that in the future, so why not start that at SummerSlam with them getting a tag run?
AJ Styles vs Ricochet vs Shinsuke Nakamura (if Nakamura or Styles win, they become a dual Champion)
I do love a good triple threat match and these three can do a lot in the win. Plus, the dual Champion card would play to Styles and Nakamura for getting involved in this match in the first place.
Bray Wyatt vs Finn Balor
Balor has requested time off, so would help to get Wyatt back over whilst giving Balor a storyline exit.
