Some of this might come up in already planned supplements but still...
Movers and Shackers A supplement on the nobles (focusing on the lower levels) and their entourage (that's mostly lacking in GT:Nobles) and the Megacorps. Information on how they interact, scenario ideas for intrigues on the courts. Give us more/new stuff on the nobility like "free" Barons (not attached to a planet/without office) and more life to the Baronett (Basically a stuffed shirt now) as well as meat on the noble orders and their interaction with high nobility.
The same supplement should/could also focus on TAS and make it more than a "High passage generator" and maybe add some other "we send you on adventures" agencies like the "Imperial Academy of Science" etc.
Tramps and Traders More background/fluff on the Frighters and their crew. From Hans Olo in his rusty 200dton Prometheus to Roi Danton in his souped up "Express/Frontier Freighter" Francis Drake. DGP's old "Starship Operators Manual" was a start but expand on that. Show us some of the workings in the lines, allow us to play Tukera/Oberlindes crews in "Explorative Trade" (like the adventure Merchant Cruiser with it's beautiful ship). Maybe introduce some organisations for ships crews (Captains Guild etc)
Twilight/Long Night SB The time between the final days of the second empire and the start of the third has many similarities to "Hard Times" but without the problems in ending it. A sourcebook for this period of time would be nice and allow for a wide variety of scenarios. Chasing pirats/raiders, diplomacy to keep a small group of worlds together/starfaring, running for needed tech, ...
Antares/Julian League SB Another "busy" sector of the 3I but without the "BRD-GDR border" element of SolRim/Spinward. An interesting boss (A Vagr Archduke) and an "enemy" that is a loose confederation of worlds. Trade, espionage, intrigue and pirat hunting.
Vagr Extends SB Okay, best done as a PDF where the map get's regenerated every six weeks
But again a territory that offers options and an unruly border. Unruly is good!
Empire SB As Kafka suggested in another thread
Oh and two "non Traveller" supplements
Polysotechnical League/Technical Civilisation The world of Niclas van Ryn, David Falkayn and Domenic Flandry. Poul Andersons work is one of the inspirations in Traveller so give us the original. Tech is not that different from Traveller, the universe is less stable and some concepts are better fleshed out
CoDominon/Future History From the early missions on Arrarat to a Moat around Murchinsons Eye. Give us Langston Fields and Alderson Drives, Saurons and Moaties, Haven, Spartha and all in between.
