Mayweather just leaked a video of a meeting with Pacquiao where he said "We have to make this fight happen". There's been a lot of buildup recently about the fight coming to fruition as well.
IMO the leak by Mayweather is a cowardly, staged publicity act to make it seem like he was the one who wanted it to happen or convinced Manny. Worst-case scenario, he could use it as his get out of jail free card to 'claim' that he wasn't the one who backed down if the fight doesn't happen. Hopefully that's not the case and the fight does go down, rendering this leak a dumb looking self-promotion by Mayweather.
