I can tell you that new books usually drop on a monthly basis, often announced in advance on the Warhammer Community site. The schedule tends to ramp up around major events like the Horus Heresy Siege of Terra finale or new Warhammer 40k/Age of Sigmar campaign launches. For example, last year, we got 'The End and the Death Vol. 2' right after the Warhammer Fest hype. Preorders typically go live on Saturdays, with digital and physical releases following the next week. I always keep an eye on the Black Library newsletter—those limited edition hardcovers sell out fast, especially if they feature authors like Dan Abnett or Aaron Dembski-Bowden. Some books also tie into tabletop releases, like the recent 'Arks of Omen' series, which synced with new model kits. If you’re into audiobooks, Black Library’s audio dramas often release alongside the print versions, narrated by legends like Toby Longworth.
