We have just 1 match confirmed so far (besides the Rumble matches). What else do you think we could see? Here's my guesses,
AJ Styles (c) vs Sami Zayn
Roman Reigns (c) vs Samoa Joe
Alexa Bliss (c) vs Paige
Charlotte (c) vs Ruby Riott
Dolph Ziggler (c) vs Baron Corbin
From these, I see only 1 title change. Alexa dropping to Paige.
