I hope they don't have Daniel Bryan go after the WWE title, since if I recall correctly, they made sure to mention that the Smackdown briefcase can only cash in on the World Champion during the big CM Punk-MITB storyline.
Their are a lot of things they could do this Bryan briefcase thing. Maybe even having two title defenses in one night like they did with Yokozuna at Wrestlemania X. Sheamus wins the Rumble, but Bryan has the contract. Mark Henry monster push has been incredible, so it would be believable that he could win both matches. In that scenario, I'd see Sheamus vs Henry first, with Henry winning, and then Bryan beating Henry later on in the night. Although, I'd rather have Sheamus win from Henry so we could get the match we didn't at last year's event.
