Yes Airship Dragoon has been Greenlit, and I just received confirmation that I am now an accredited Steamworks developer. HUZZAH!
Thanks to everybody who voted it through Greenlight.
They'll be another update in the next week or so with additional troop models, reworked mountainous environments, a few customer requested functions/changes and a bug fix for a lockup issue which was introduced in version 1.4. They'll also be the release of the "realism mod" which replaces all the models and textures in the battlefields with fancy hi-res environments.
For a preview of that, check out my devblog http://yorkshirerifles.blogspot.co.uk/
