The funny thing about superfights is time after time there rumored and time after time again nothing happens yet that doesn't stop the masses from taking the rumors seriously. Besides GSP v Penn at UFC 94 no two reigning champs have ever fought in a title bout and besides Aldo v Pettis(which has a better chance of not happening than happening) there probably won't be for years to come. The superfights era never even started it was just a UFC tactic to get people talking about who the greatest was and get more pumped for GSP, Silva and more recently Jones ripping apart lesser opponents. Superfights in general are bad for long term business for the UFC because while a superfight makes money someone loses and makes a lot less money long term than they would've.

People are saying the Super Fights are gone since Anderson lost as if they wouldn't watch GSP vs Anderson or Anderson vs Jon Jones if they were put on. They'd prefer to watch main events like Kennedy vs. Natal or Rampage vs. Tito.
Dana said if he lost the superfights would be out of the question. Anderson said no, no problem, I still can superfight. So make of those conflicting statements what you will.
Cain vs JDS, Shields vs Maia, Mighty Mouse vs Benevidez are way more appealing and will do better PPV buys and live ticket sales than GSP vs Anderson or Jones vs Anderson could ever dream of. That's why super fights are out of the question. No one will pay to watch them. They're not fights with title implications so no one cares.
