So exciting time for the First Order... by my count FFG should be developing four FO ships.
The First Order Interceptor seen in Star Wars Resistance.
The Xi-class light shuttle seen in TLJ
The “Mark 2” TIE Silencer seen in the TROS trailer (does it have an official name yet?)
The TIE Dagger as seen on the cover of the TROS visual dictionary (thanks to @Imperial Advisor Arem Heshvaun )
