I'm sure that they will do one. They do one for every PPV show, and they will do one for what they consider to be a "special event" free show.

HBO benefits from these shows, because they help sell the event, thus more PPV buys, resulting in more money for them.

They've had Cotto in 2 already (Judah & Mosley), and they've done shows where they had to use translators (Marquez & Morales), so I don't see whether or not they speak any, or good English, being a factor.
