All these ships will be completed. The ISC fleet is nearly done all that needs to happen is make little weapon models for them. I'm working on the Kzinti Light Cruiser (ZCL) as we speak, in fact. These ships are going to be used in an SFC mod that some people over at Dynaverse are working on, so yes, they will all be completed.
I also plan on remaking Gorn, Lyran, and possibly Hydran - All the while going back and playing with my Romulans, too.
Furthermore I do plan on playing with lesser-known races that won't even be in the mod: Vudar, Triaxian, Frax, and Seltorian - Plus a few TNG races that will be brought "back in time" into a TMP look: Sheliak, Cardassian, Talarian, Ferengi.
Not only that, but I will also be making a fan-made race from SFB: The Borak.
