I think Cena should drop the championship to Sandow. After ending his feud with Rusev at Payback, with Rusev winning at Extreme Rules and Cena winning back the title at Payback, he competes for the world championship ladder match at MITB but comes up short, while Sandow competes in the MITB ladder match and comes up short. Sandow comes out the next night and talks about how his career was damaged after losing to Cena, and they can have a slow build for the match heading to Battleground, although I'd save the match for Summerslam, where Sandow beats Cena to win the title.
Daniel Bryan after feuding with Barrett and Sheamus, can start a long summer feud with Ziggler, probably for 3-4 PPVs, starting from Summerslam.
They can have a singles match at Summerslam, a ladder match at NOC, a hell in a cell match at Hell in a Cell and finally an iron man match at Survivor Series, with Ziggler finally winning the championship from Bryan. Or, they can have Bryan regain the title in the last match and have him drop the championship next year at Wrestlemania or before that to someone younger, like say... Neville?
