I was recently thinking about what "Clone Wars is coming" might mean. My first guess was a new core set, similarly to X-Wing with new era stuff. So I started thinking that squads would likely be Vultures and Torrents, so they could release the more potent Tri-fighters, Hyenas, Belbullabs, ARC-170s, V-Wings, Y-Wings and Eta-2s in a squadron expansion. But then I realized that we would need two small ships on one side and one medium for the other, and that's where it all went wrong. What small sized ships either faction may have that is iconic enough, useful on its own and wasn't released before as a GCW ship? And the answer was.... none. I can't think of any ship for either the GAR or the CIS that would be a suitable small ship for a core box. Mediums sure, but not small ones.
So my guess now is that the Clone Wars will mean the release of at least one (but more likely two) ships for each faction, alongside a pair of Squadron Packs, and hopefully conversion kits for those ships that were used in the Clone Wars (VSD, Gozer, Kitten, Pelta). Of course I would love to see a new core set (at least I would have two damage decks and some extra dice), but I can't find the ships for that.
