Just found this so i was right

"May 5th is kind of soon," said Roach. "For a fight of this magnitude to happen you need time, you've got to promote the fight right, and again it's about negotiations: who's going to get what. Is it going to go 50/50? He (Mayweather) wants 70/30, there are a lot of details to be worked out and the May 5th date is a little bit soon.

"Manny had that cut in the last fight and we want that to heal properly so we were looking forward to a June date, but I think realistically for this big a fight we would have to spend more time promoting it. I don't think that's something we would want to rush."
