User blog comment:J Fan/Pirates 5 - Sequel News Rundown/@comment-1984959-20130818190201/@comment-1984959-20130818205707

Taking from the news article, we do know that the Pirate Lords would at least make an appearance. Who knows, they might decide to bring one or two Lords back in P5. Whether that means there is an actual Brethren Court meeting or not is up to speculation, considering we don't know yet if it's really part of the film's plot.

Hypothetically speaking, of course, as we don't know if this news will remain accurate, or if the Brethren really is in one of the screenplay drafts. Should note that this is currently the only article covering the story.
