Combat Manuals (Davion, Steiner) - Thanks, Harmony Gold!
CM: Davion had been back-burnered well before the HG suit was filed in March, and certainly long before that suit was publicly noticed two weeks ago. As has been stated (more than once, IIRC) in a previous Upcoming Releases thread, the CMs are art-intensive and expensive to produce, and need to sell well in order to justify future volumes. I'm still nominally under contract to edit CM:D, and have been for more than a year, but for months there's been no indication that I'd be starting on it any time soon.
Certainly, the presence of the suit likely creates significant issues with the CMs, so you're not wrong in your statement. But it's worth re-iterating that the book was not seeing much movement even before that happened.
Other PDFs (Milestones, OpFor, Spotlight On, Touring the Stars) - please?
There's a number of Touring the Stars and Spotlights On in the hopper, at various stages in the editing and/or layout phases. Hopefully, with the convention-related product rush out of the way, you'll start seeing regular releases of them again.
