While I was thinking it could happen before, now with Pacquiao's fight against Clotty doing 700k and Mayweather and Mosley more than likely doing double that, I don't see Mayweather going for the 50/50 purse split and he's definitely not budging on the random blood testing. Add to that his decimation of a guy who Roach and Pacquiao wanted no parts of, following a total shut out of the guy who fought Pac to a standstill and he becomes a less attractive opponent.
