Got an email today from my SA. Apparently my Gravity order has been assigned to a batch #, which represents progress, but doesn't come with any specific estimate for production dates. GGT, White, 5 seat, 20"/21" wheels, and with HUD. So yet another sign that the issues limiting production are being addressed, and things are ramping up.
All in all, I'm not sad about a likely production date in Q4, as I'm happy to miss the worst of the first quarter of teething pains being discussed here. And I guess I'm happy to not have a vehicle produced during an end-of-quarter push to show better numbers.
