I think this angle has accidentally stumbled into some twisted brilliance. Bryan's chase isn't the title anymore, it's the idea that HHH really wants to bury him. Maybe they do, I have no idea. But they'll build this match with that Rock-Cena meta-vibe and I think it's going to be genuinely compelling to see whether or not Bryan actually wins, and how. I think having the title involved at this point would take away some of the drama of Bryan conquering, because it would be an obvious feel-good ending. This is more mysterious, and interesting, to me from both a storyline standpoint and "real".
Also they got 20,000 to chant for the match after Bryan came out and said that's the match he wanted, so, they got a good visual and momentum for it.
