I would just be happy if they kept plugging ahead with one kit from each of the three main eras a year in the standard scales, in addition to whatever else they do. Would be nice to start getting some Prequel coverage. There's a lot to mine there in the way of interesting designs that would appeal to both modelers and collectors. Especially if you include Clone Wars and Rebels in there, and all of the nose art, paint variations, etc.
I'm fine with only one truly big kit a year. We got the ANH Falcon, we're getting the Star Destroyer... It'd be nice if we got a 1:72 Slave I or Ghost... A 1:72 Lambda-class and/or Nu-class shuttle would also be brilliant, and big enough I'd figure those to be among their less-frequent "big box" releases... I'd love a partial re-pop of the Falcon with ESB/ST front-lower quarter. And a Lando body kit would be fantastic -- wouldn't need to invest in a full-on tooling for a kit the size of the Falcon, with all the details and greebling. Just the escape pod and hull plating to fit over the existing 1:72 Falcon kit.
But the standard starfighters in 1:72? Gods below, if we could keep gradually filling in those holes. V-19 Torrent, ARC-170, Z-95 Headhunter, Clone Wars Y-Wing, Rebels Y-Wing, Mandalorian Fang, Alpha-3 Nimbus "V-Wing", Delta-7 Æthersprite (including variants), Eta-2 Actis, LAAT/i, the various droid fighters, Grievous' "Soulless One" fighter, his Magna-Guards' fighters, both Phantoms, the nonzero number of TIES yet to be done, the T-85 X-Wing, the other racing ships from Resistance... There's enough just in recognizable material like that to keep them going for over a decade.
...If points of purchase know to stock them! I'm fortunate in having a couple of LHSes that make efforts to keep decent selections of genre kits on the shelves in addition to the other cars, airplanes, armor, and RC stuff. And online sellers like Bluefin (which is owned by Bandai, so there's that) or USA Gundam are good, but there need to be more chain stores that stock them for people who don't know to look for them to stumble across. Which gets into the whole matter of shrinking interest in physical play afflicting at least America. There are kids who build models and play with action figures and so forth, but it's nowhere near as ubiquitous as it was a generation ago. Enough "kids these days" are only interested in digital entertainment that the toy and model industry has been repeatedly reworking itself over the last decade or so to try to figure out how to stay relevant. And chain retailers like Target and Walmart aren't helping. That's where a whole lot of people shop for everything. And they tend to have toy departments run by people who aren't in touch with current cultural trends. My local Walmart sucks at ordering Star Wars action figures, for instance. They'll over-order one wave, most of which will rust on the pegs, and never order more because "they're not selling". Never realizing that people are wanting the newer waves that have come and gone -- but not here.
Part of that is also Hasbro ongoingly mis-packing said waves. Misjudging how many people will be needing this Rey figure, and drastically underestimating how many will want that Darth Revan, for instance.
So get your kids into building models (I started at age 7). Encourage local Scout troops or youth centers to include building models among their handicraft tutelage. Generate a local geek-focused hangout spot. The good old comic-and-gaming shop is a good one. Best way to encourage Bandai to make more models is to have more sellers stocking them and ordering from distributors. Best way to ensure that keeps up a good clip is having actual end-users buying the flipping things. There are a lot of people out there who'd love building models, but they never knew it was a thing. I know -- I've met some. I would be talking about general geek stuff and conversation would wend in a direction that I'd mention some model that I'd gotten that I was intending to mod or accurize and they'd be utterly poleaxed that this was actually a thing one could buy and do.
