It sounds like the core of the Undisputed dispute was the contract for likeness rights, which would entail Fitch signing away those rights to the UFC in a lifetime deal for use in THQ's game. The earlier reports on this have quotes from Fitch about how he wanted to negotiate a shorter-term deal. The response from UFC, apparently, was to boot Fitch and other fighters from the American Kickboxing Academy team that he represents out of UFC. According to MMAjunkie, here's a classy quote from the president of UFC, Dana White on the subject.
"We're looking for guys who want to work with us and not against us, and frankly I'm just so [expletive] sick of this [expletive] it's not even funny," White said from Honolulu, where he flew Wednesday from Toronto to hold a news conference to announce the B.J. Penn-Georges St. Pierre fight for UFC 94 on Jan. 31 in Las Vegas.
"Affliction is still out there trying to build its company. Let [Fitch] go work with them. Let him see what he thinks of those [expletives]. [Expletive] him. These guys aren't partners with us. [Expletive] them. All of them, every last [expletive] one of them."
Nice.
In a later quote in the story, White went on to say "I'm not a douche bag." Sorry, dude. If you have to come out and claim that you're not a douche bag, you're most definitely a douche bag.
Today, MMARated, another MMA-focused blog, posted updates on the situation, including a video interview with Fitch where he claims he has signed the deal and that the whole thing was about respect and Fitch not liking the way White was coming at him over all this, and that the terms of the contract were never a big deal. Considering there are already quotes out there where Fitch questions the need for a lifetime deal, this seems... uh... untrue?
