I think it's going to be Ospreay
[Disclaimer] Didn't watch this mornings show yet show I don't know the results yet so my reply is based on that.... [/]
I was thinking that too, but he's scheduled to face Jeff Cobb in a title vs title match at MSG right now. Other than him you have:
Okada - White has owned him storyline wise. Too soon to go there again.
Tana - just took the belt off him, there wasn't a rematch, but still similar to Okada.
ZSJ - Won last year, can't see him winning 2 years in a row but, maybe.
SANADA - possibly, he'd probably be my favorite right now if I was betting.
Cabana - No.
Ishii - maybe, wouldn't surprise me. It would be a good match.
Yoshi-Hashi - lol no.
Hopefully they don't go back the Okada/Tana well. As good as the match would be, and I know they probably want their stars headlining, I just don't think it will make much storyline sense. Rather see SANADA/ZSJ/Ishii. With that being said it will probably be Okada or Tana.
