Exactly what the next-gen Zods could do would depend on the design we ended up finding fun, but it would probably be all about player power and getting rid of gameplay annoyances. Very fast resupply, onboard self-repair and self-regen, maybe some kind of 'supermaneuverability' (glide, blink, I dunno). Maybe some Gundam bull**** like armed drones you could deploy and recall. Systems that rewarded getting in close and mixing it up, Doom 4 style — man, a ship that rewarded ramming would be SO cool.
If the Terran GTVA's 'color pie' (their slice of gameplay mechanics, their design theme) is TAG, drones, small fighters and beam-armed warships, and the UEF's color pie is superfighters, missiles, and projectile weapons, then the Vasudan color pie would need to bring something new. A big theme was/is going to be the divide between Imperial Vasudan Navy line units and the 'royal guard' Medjai.
Fighter models would probably come from Inferno/Earth Defense.
There would also definitely be next-gen Zod capships. We talked about using Esarai's ships if we didn't find anything better.
