Pinged Jason earlier this week and he passed along some info:
Upcoming Releases
Dark Terrors - print release upcoming
SR5 Core Rulebook - reprint w/ errata (hardcover)
Toxic Alleys - stand alone adventure that has loose ties to the Denver adventures and Dark Terrors (to help bring some chaos to DeeCee)
Pipeline
Street Lethal (advanced combat book): more weapons, including some future tech, info on corp security and unconventional fighting forces, and new maneuvers for tactical combat
Kill Code (advanced Matrix book: all the stuff slated for the technomancer ebook--complex forms, streams, alternate TM builds, and more--as well as decker gear and qualities, a guide to running the Matrix, and other useful stuff for Matrix-based shadowrunning
Better than Bad ("hooding" book): focused on how to run with a conscience, and provide info on Pretoria in Azania
I also asked him re the potential for elf / dwarf books, but nothing approved or in process, at the moment.
