I think the infantry kits have been a great source of sci-fi figures and bits, and I think the vehicle kits look fantastic, so I hope to see more from this product line!
I seriously wish we had good variety of generic 28mm Heroic - or at least 1/48 scale model - vehicles, artillary, and accessories for use in skirmish gaming, in various periods.
That Iron-Core APC looked like a fantastic model to work with, and I'm sorry I missed it when it was available!
I also liked the accessories set - the one with the "robot mules", and a bunch of spare heads, arms, gesturing hands, and guns in it; I bought a couple of those, and bits from those kits make it into my kit-bashing projects all the time.
I'd love to see a better, more well-rounded selection of model kits and vehicles in roughly 28mm or 1/48 scale to work with, both sci-fi and historical. I think that for sci-fi and near-future skirmish gaming - say for raids, "capture the flag", "defend the objective", and other style scenarios - we could maybe use an artillary piece, an APC/IFV, a comms/sensor array, maybe things like drones, power-armor, and sentry guns... I don't think a huge variety is needed, just a generic kit, with enough options to dress things up a bit for using the kit with different factions. Wargamers in particular, I think, would want more variety than that, but even generic one-size-fits-all-factions kits are more than is commonly available now.
Historical gaming might work best with something a little more specific, of course, but 1/48 scale modeling does produce a limited selection of very nice models that can work at least for WWII gamers (you get slim pickings when you move very far away from WWII, though: modern kits have weird gaps in what's available, and WWI kits are all but non-existent, for example!)
Anyway, I like the Death Fields Command and Heavy Support sprue for supplying a fantastic variety of gun emplacements that can be used for a variety of sci-fi contexts, and would have loved to have seen the Iron-Core APC available,as it looks like a fantastic model that could have been used for all sorts of different sci-fi games.
