Mostly commenting to follow, but definitely count me among those eagerly awaiting the rebirth. Can I finally retire the "fan made" Combat Manuals!? 
Oh, just wait until you see my Force Manual: That One Faction That Appears As An Offhand Mention In One Or Two Sourcebooks That I've Been Obsessed With That Will Never Get An Official Force Manual.
Honestly, it's for stuff like that I hope that some day, we get multi-faction Force Manuals that are a compilation of smaller forces. I badly want as Force Manual: Conspiracies book with lore and rules for the special ops units of the Inner Sphere's intelligence community, the Saurimat, the Thugee Phansigars (assuming they're not rolled into WoB), The Society, and so on—maybe even the Cult of St. Cameron. If it sells well, maybe it could get a supplement covering some of the secret societies, cults, and other underground movements that took the chaos of the HPG blackout as the opportunity to act (White Hand, Bannison's Raiders, Daughters of Kali, Cult of St. Apollyon, etc.).
Any Force Manual that could find a way to fit the Ebon Keshik in would be awesome as well.
