Well, based on what Cannon said when queried about why there were 3 Equipment slots on the juggernaut when realistically you'd only need 2 (jump drive/scanner module) that future modules/devices are coming.
What do you think they're will be?
Because honestly I can't think of anything else besides the ones that are here or will be.
Player docking... been wanted for several years to make carriers useful. We'll have it soon'¢
Cloaking. Here, pretty good for transports/battleships. Little tweaking needed for Gunboats, Fighters/Bombers/Freighters.
Jumping. Possible, most efficient when the scanner module/jump drive are on seperate ships.
What else could their be?
In addition, the number of module slots on the higher-order core upgrades makes me suspect future modules for bases are coming...
I find commodity factories to be interesting.
No, not to where a base could sustain itself even partially with its own factory, but in the same way cloaks/jumps/docking modules/scanner modules are only produceable via player bases, these commodities would only be availible from player bases.
They'd sell for quite high around Sirius. Perhaps more specific, higher quality commodities branching off from what are already here.
Coffee, Beer... But not only that, perhaps higher quality manufacturing equipment.
