It's definitely not dead, the last update (mainly the VW Scirocco) just takes a lot longer than expected because the devs found some flaws in the physics while adding the VWS so they (or rather he, Scawen) basically had to do the whole physics from scratch which obviously takes some time.
Scawen's latest posts make me hopeful that there will be a Test Patch coming this year but nobody knows for sure when the exact date will be, probably not even the devs themselves.
