This is purely speculation based on confirmed information, data mined information, development patterns, etc. Spoilers may follow:
So the weekend event has reached its 16th. And the final weekend event item(a jetpack flame color) is about to be unlocked soon. The quicksilver synthesis bot hasn’t put up any of the new base-building plants, or space-ship related cosmetic items(bobbleheads and flame trail colors) that was data mined to be purchasable.
Anyone else think that a future update is going to be related to spaceship customisation? My guess is that the U.I. will be like the suit customizer. Perhaps that’s the way to apply the new flame trails and bobbleheads.
