I've come to accept they'll hold off until some theoretical 'version 2.0' in the future. Note that this is entirely theoretical, though.
They tried an update with the Force Awakens set, but without changing the cards in the original box (and they've never updated a product after shipping it, even for explicit errata on reference cards), they're stuck with people able to buy into the hobby who would legitimitely have only one damage deck - the old one.
I suspect in the theoretical 2.0, there'd be a bunch of upgrade cards for pilots, a damage deck, and... eh, who knows. But I suspect they'll have a GPL-style rule that means that rule updates can be printed and supercede older reference cards without making the old stuff illegal; that way they can keep things from being so disjointed with the FAQ going forward.
