Just read an interview with Dana White where he said that the champion needs to clean out the division. He said that the fight in August between Florian and Huerta would give the winner the first fight againt the Penn/Sherk winner.
This could lead to some great fights. I see Penn finishing Sherk within 2 rounds as I also see with Florian over Huerta. A Penn/Florian fight could be very interesting imo. I think Florian's game is solid enough to last a bit, but in the end Penn would finish him as well.
