The Aerospace Engineer's Handbook has been pushed back due to the planned release of the new version of Traveller.
Atlas of the French Arm is in layout right now, and should be out fairly soon. I am currently working on Aliens of the French Arm.
As noted above, Gavin has finished the Bayern campaign, and I just have to give it a final review.
There will be an announcement in the next month or so about 2300AD and the new edition of Traveller.
Beyond that, 2016 should see the release of Aerospace Engineer's Handbook, Mission Arcturus, Atlas of the Chinese Arm, and likely Ships pf the Chinese Arm, along with possibly Chinese Arm Adventures. There are three adventures in the process of being written by other authors, along with some military sourcebooks (French Foreign Legion, Texas Rifles, and Russian Rapid Response Group). There may be 1 or 2 other products coming out in 2016 as well.
