They're honestly still thinking about doing a Triple H/Brock rematch? That feud ended just fine with Triple H realizing what a monster Brock is and didn't he give a speech about how he was sorry he let people down? There's no logical reason for him to get 'revenge.' Ryback/Brock would be a much better choice for Wrestlemania, but of course, they don't want to end the streak. But I don't want them to end Punk's long title reign before the Rumble, and besides, they can't hotshot the belt onto Ryback, because Rock has already made the challenge for the Rumble, and they're obviously building towards Rock/Punk for that event. And giving the belt to Ryback only for him to lose it right back to Punk would still mean the streak coming to an end.
Either way, seeing WWE backed into a corner like this, it's gonna be fun to see what they end up having to do.
