Its mainly a publicity stunt to keep himself in the spotlight...
He's been mentioning going on hiatus for two years after the Hatton fight, switching to MMA, and the possibility of returning to fight at Light Welter or Lightweight.
Floyd loves the money though, and will go wherever bring him the most

Can't blame him too much though I guess...
In MMA, his boxing skills will be redundant - every opponent he faces will know how good he is in the stand up and realistically knows they have little hope against him and will go straight for a takedown...
In boxing so far, he's been able to adapt his technique to defeat every opponent, so I wouldn't doubt his potential in MMA
