To be honest i hope one of the 2 organisations does send the other out of business. The only way MMA will evolve into a truly global sport (which it definitely has the potential to do) is through unification. One set of rules, one configuration of fighting arena and fighters competing for one set of true world titles at LW, MW, LHW and HW.
Evolution at its most magnificent.......... survival of the fittest!
Charles Darwin - "In the natural world, evolutionary speaking its not the most intelligent or the strongest organism thats the most successful but the most adaptable and versatile."
