There's already several different fighters for some of the Warlords and more are coming in 2.3. Pentastar gets the V-19 Torrent, Maldrood gets the TIE Avenger and ARC-170, and Eriadu gets a shielded TIE Interceptor. In 2.3, they're adding the TIE Punisher to Eriadu, but I'm not sure if they're adding other fighters to the other warlords for that release. I know Corey has said that eventually they'd like to get some different fighters like XG-1s in for some of the Warlords.
