HA HA HA! YES! In a cutscene following the mission "Butterfly Master", the emblems for the Antares and Varcolac squadrons appear as "ace pilots" in the UNF and Bone Arrows. This, for me, is confirmation that the Varcolac and possibly Fenrir will make an appearance in either the storyline or at least the game itself.
The emblems can be seen at 21:48 of the video below.
