From a business perspective, the UFC is facing a year without their two biggest PPV draws, Georges St Pierre and Brock Lesnar. Therefore, expect the UFC to try and make the most sellable fights out there. That means Silva vs Sonnen 2 will happen, surely, and I expect Bones vs Rashad will as well. They need fights with stories to shift some sales. :bbb
I'd be very surprised if both of those fights didn't happen this year. I'll be interested to see how JDS v Overeem does with the PPV numbers as well.
