The prequels don't match up to the magnitude of the originals, which have 30+ years of fans who grew up with the quintessential space opera. The gaffes in the original have long been overshadowed by what made it great: Vader, the struggle of good versus evil, and resolution of destiny. The prequel dropped the ball on the first two points while trying to capture the third. "Vader" is presented as being whiny and unlikable. Both sides of the clone wars are ultimately lead by evil characters, but Aniken meets his destiny and becomes Darth Vader as he was supposed to. And so on...
Anyway, it doesn't appear FFG will revisit the prequels. The H-9 Scurrg is really an exception to the whole of the prequel era sitting in the background of FFG's focus. There is no precedent for them to revisit that period and no real inclination to start here in Armada. If the prequels are going to happen, it'll either be in the RPG or X-Wing (both of which already have established fanbases that can take that kind of shakeup).
