To be fair; Im not keeping it "that" fresh though
The last serious update was a couple of months ago, and the next major one's Release Date is TBD.
But what is a bit more interesting is a newly announced Mod "Star Wolves 3: Bounds of Consent Anthology" for SW3 by ProtokSt at ModDB

The Mod's goal seems to be to combine all 3 games into one huge Storyline driven game (which includes The Legacy Mod for SW1, which was a Russian only localized mod)
