Mark Henry should feud for the WWE Title at some point. He's an original opponent for Cena. They're already setting up Cena/Ryback for Extreme Rules (or possibly a triple threat) but they could always change it. There's still five Raws left to the PPV. Maybe Henry gets a title shot on Raw in a normal match. The match either ends in a DQ or a draw or whatever, and Henry takes out his frustrations by bear hugging and slamming Cena against the ring post and then smashing him through a table. Somehow, Henry gets a rematch at Extreme Rules and Cena has to go into the match with taped ribs or something, but manages to overcome Henry and defeat him. I'd personally rather have the first normal match on PPV and THEN the No DQ match at the second PPV since this feud could be stretched out over a couple of PPVs but Extreme Rules is the next one in line, so...
And wouldn't Henry jumping into the title right now be the logical thing anyway? As mentioned, it's kind of odd for Henry to win a match at Wrestlemania and then have his opponent whom he defeated get to challenge for the world title while Henry drops down the card. Ryback has lost every major match he's been in - which by my count is seven - and is now fixing to lose another one. It's that kind of illogical booking that gets WWE laughed at by myself.
