They will. It's their choice if they want to speak English in respect to American viewers, but subtitles go a long way.
they will speak in english and there will be subtitles for both... shiet! they need subtitles for the entire wifebeater clan... those mofos can't speak a lick of proper english either without mumbling or stuttering.
That would be dull man they need to both go have good english lessons so the 24/7 would be good no point trying to promote the event with the 2 fighters with crappy english

Same situation (Marquez speaks MUCH better english than Margarito) and look how that turned out despite a 'boycott' and 2 guys who speak limited or no english. 1.2 million buys. Pacquiao-Marquez III will blow that figure out of the water.
