I'm not involved, other than as a backer, but there's a Kickstarter underway for ZN Games' miniatures (the full story is on the KS page) that include a bunch of 6mm fantasy/steampunk airships and some giants/stone guardians and an awesome hut-carrying giant turtle!

The airships generally seem to be for one faction, although the smallest ones look different enough they could be another, and some insect-like bioships were showed on TMP that might be a stretch goal.

I'm in for a bunch of ships, plus some stone guardians, and a couple of those turtles (for my 6mm Lizardmen army).

The rest of the KS is for 28mm fantasy figs for those so inclined.
