This one is tough to say, but I would speculate unlikely. The new DirecTV 14 satellite has beam aimed at PR that they are putting some HD channels on mirroring with the ConUS beams. Creative bandwidth management to summarize.
DirecTV Caribbean comes from different satellites and different aim locations, which doesn't mesh with what they are doing to enhance PR.
So, if it does come to Caribbean it is unrelated to the new satellite bandwidth, which is why I believe unlikely.
