Season 2 spoilers?
Quite possible. Since it seems like FFG may have been mandated to add Rebels stuff, it's possible that someone talked to someone that actually worked on the show and they gave them the specs of the ship, including systems that haven't been shown on the show yet.
Is there any evidence at all that FFG was mandated to add anything? It seems simpler to assume that rather than Orders Arriving From Above, the scenario was more like "Hey, what can we draw from for the next wave? Rebels has some cool ships, right?"
