I'm looking forward to the Acclamator-class myself. Dunno why, but I like that ship. Then again, I don't think it's currently cannon. You never see one in the prequels, and did it ever show up in Clone Wars? I know it was in Rebel Commando, but that counts for nothing. Always been a fan of the Venator, too. It's a shame about Dinsey clamping down on Clone Wars stuff. I've always thought it would be great of FFG to do things Flames of War style - have Early War (Clone Wars), Mid War (GCW) and Late War (FA-era). You can use early ships in a late game, but their point cost is lower because they're crap by comparison.
I wonder if they'll bring back things like the Carrack cruiser or Corellian gunboat. Hell, I even think the Interdictor cruiser is non-cannon at this point, unless it's been in one of the new books. And didn't there used to be a dedicated escort carrier for the Imps? I seem to remember one from the Rebellion video game. That'd be an interesting one - a ship with a lot of HP, very little maneuverability or offensive firepower, but plenty of room for squadron upgrades and a high squadron value.
The Acclamator is 100% canon. It has multiple appearances in the Battle of Geonosis and the rallying on Coruscant, as well as the canon Clone Wars TV show. The Rebels TV show has introduced Interdictors and Quasar Fire carriers for their respective factions, as well as the Hammerhead things.
