What are the chances of?

On May 5 mayweather vs. cotto for the main event canelo alvarez vs. shane mosley as main undercard and On June 9 pacquiao vs. bradley for the main event donaire vs. arce for the main undercard Someone online mentioned that this was a possibility (not a credible source). The mayweather and pacquiao main events are good fights imo. Cotto will put up a good fight and Bradley is young and prime. Alvarez is a hype job but it's a decent fight for the young buck to fight a past prime old man coming off a loss. I would have preferred Donaire to fight Nishioka. But the arena in the Philippines is opening in May and Pinoys there seem to want that fight. Thoughts?
