This image from the Capcom-Unity blog's whiteboard would certainly indicate Capcom USA is planning to sell the Rockman 9 Original Soundtrack on their online store. Since it's the Rockman 9 soundtrack (as opposed to the Mega Man 9 soundtrack), it seems the albums will just be imports, and not translated for western buyers. Nevertheless, Capcom could be getting a reading on how well Mega Man soundtracks would sell outside of Japan. With how popular video game music has become, it's a wonder more companies don't try to sell game music stateside.
