Naboo N-1 and Belbullab-22.
Literally the only ones I can find from the right era(ish) that aren't just variants of ships that are already in the game.
I'd like to hope that we'll get more coming in the new canon. But the next one likely to be (re)introduced in Rebels is the X-Wing.
And if ep9 brings us something different, that too will more than likely be just a suped-up version of an OT ship, like the T-70 was.
Is there anything (good) I've missed?
