Ziggler will win MITB because he'll never make his way into the main event if he doesn't. Alberto Del Rio, for whatever reason, is consistently in the title picture. Soon Orton and Barret will be back. This is Ziggler's only opportunity. Don't expect much for Ziggler come Survivor Series or Royal Rumble, unless he has the briefcase.
Besides, the MITB match for Smackdown, is a complete cake walk for him to win. Zero Competition in that one. Tensai ain't winning and no matter how much people love Damien Sandow and Tyson Kidd...give me a break. Ain't happening. MITB is Zigglers.
