What's gonna happen on RAW? Viewing it from both a credibility and storyline standpoint:
𝑪𝒓𝒆𝒅𝒊𝒃𝒊𝒍𝒊𝒕𝒚 - Both Dom & Oba need to be protected here. You simply can't squash AAA's Mega Champion especially since he's gone toe-to-toe and often beaten the likes of AJ Styles, John Cena, Finn Balor, Penta and Vikingo.
Oba needs to be protected because he's soon gonna be challenging for world titles. They have him running through half the roster in 2 minute squashes. But the squashes have reached the point of diminishing returns. They're not really helping him anymore. He was having longer, meaningful matches in NXT.
𝑺𝒕𝒐𝒓𝒚𝒍𝒊𝒏𝒆 - Dom has a few storylines stacked up the next few months. One with EGA in AAA, possibly a retirement match with Rey, and he's a favorite to win MITB. So he really doesn't need the KOTR crown right now.
Oba is slated to challenge for world titles, however he's still in a feud w/ Brock.
All that to say it's probably 50/50 on who wins the match.
