And the next issue of Vader is out, and reviewed, Darth Vader: Issue 41: Dark Droids: More Machine Than Man. It feels like the end of the Dark Droids storyline, although nothing is resolved, but it's a big fight, and that seems to serve this series as a conclusion to a storyline, especially as they spend the last couple of pages introducing the next big bad to be faced, the Schism Imperial.
