So looking back at the matches as you said:
Bray vs Orton
AJ vs Shane
Cena vs Ambrose (replace with Corbin)
Goldberg vs Brock
Reigns vs Taker
HHH vs Rollins
KO vs Jericho
Show vs Shaq (if it even happens??)
Andre Battle Royal
I-C ladder match (if not Ambrose/Cena)
2 women's matches
1 if not 2 tag titles match (1 more likely if battle royal happens)
Cruiserweight match?
And then Joe, Balor, Strowman doing..?
That's like 15 matches when you take the pre-show into consideration. :huh:
