I checked the descriptions of Stalker Fighters and Fer'jai Frigates on Tribble and noted the new entries to the ship restrictions: Fleet Caitian Atrox Carrier and Fleet Kar'fi Carrier. Speculation time?
Generic answer: I'll believe it when I see it in the game proper.
To add to that: That'd be nice and all, and I hope that it happens. Haven't had any fleet ships added to the other two factions in quite awhile, not to mention people have been itching for more Fleet Carriers for awhile.
Might even get me to buy the Kar'fi if they put that sucker out as a Fleet ship.
