Hexis shared with me today the 2014 FFG In Flight Report at GenCon filmed by Team Covenant and uploaded to YouTube. CEO Christian Peterson's answer at 1:15:00 should put the Prequel question to rest for a while. He said (sloppy transcription):
"We're not planning on integrating anything per se in the style of, for example, the Clone Wars cartoon, but with that said, vehicles, characters, storylines, etc that came out of that, those cartoons are part of Star Wars IP [intellectual Property license] in general, and I can't speak whether some of those ships that are shown today were maybe in the cartoon. I haven't seen them all, so there may be things where you sort of say, ah! that's from the cartoon, they're looking at the cartoon.
More generally we're looking at the sort of game as it is, the Galactic Civil War going way forward , and we're going to try to, we have a significant amount of content, and we're going to throw in some new content with the new cartoon set in that era. We would not ever put out a product I think that would like the cartoon characters which has this very unique kind of look and stylization to them, but obviously we're thrilled if there was some awesome new type of starfighter that was revealed to us in the Rebels TV show, for example, we would take a very hard look at trying to integrate that into our future plans."
