Just the fact that it's already been announced that Balor will wear the face paint pretty much puts a lock on this match. I don't think he's ever lost wearing it, and Wyatt doesn't strike me as the one to end that streak.
It's been a pretty boring feud overall, then most of Bray Wyatt's are these days. Even with the unusual character that he portrays, none of his smoke and mirrors ever seem to work.
Unfortunately as with most of his feuds he will probably come out on the losing end of it. He has a couple of wins over Balor or far and that usually ends with the loser of the RAW feud winning at the PPV.
To be honest this feud should be on the preshow, that's just how boring it is, but with Balor putting on the paint it will be on the main show.
