All of the Fall/Winter catalogs are pretty much out by now. In terms of books that interest me directly, it's not fat pickings, but there will certainly be more coming as many are not announced far in advance.
* Stoneman's Raid, 1865 by Chris J. Hartley (John F. Blair).
Check out the table of contents from the linked page. It looks great, and, in the meantime, you might check out the author's Blue and Gray Magazine feature article and General's Tour on a portion of the raid.
* Summer Thunder: A Battlefield Guide to the Artillery at Gettysburg by Matt Spruill (U. of Tenn Pr).
Online sources have this for a mid-August release, the publisher mid-September.
* Failure in the Saddle: Nathan Bedford Forrest, Joe Wheeler, and the Confederate Cavalry in the Chickamauga Campaign by David Powell (Savas Beatie).
* The New York Times The Complete Civil War 1861-1865 edited by Holzer and Symonds (Black Dog & Leventhal).
This book and DVD combo will be a valuable reference book, with 600 articles reproduced in print and 139,000 more articles -- the complete Times run -- in the digital companion. I would never have guessed anything approaching that number. The newspaper maps will be included, as well.
* Into the Crater: The Mine Attack at Petersburg by Earl Hess (U. of SC Pr).
* The Day Dixie Died: The Battle of Atlanta by Gary Ecelbarger (Thomas Dunne/St. Martin's).
Finally, a full length battle history from this campaign.
* Railroads of the Civil War: An Illustrated History by Michael Leavey (Westholme).
* Border War: Fighting over Slavery before the Civil War by Stanley Harrold (U. of NC Pr).
* Crossroads of Conflict: A Guide to Civil War Sites in Georgia by Brown and Elwell (U. of Georgia Pr).
I'm hoping the coastal sites get a lot of attention.
* A Civil War Gunboat in Pacific Waters: Life on Board the USS Saginaw by Hans Konrad Van Tilburg (UP of Florida).
The archaeological-historical studies from UPF (at least the ones I've read) are always good.
* The Notorious "Bull" Nelson: Murdered Civil War General by Donald A. Clark (SIU Pr).
* I Will Give Them One More Shot: Ramsey’s First Regiment Georgia Volunteers by George W. Martin (Mercer U. Pr).
A mega regimental of a one-year unit that fought in theaters of great interest to me.
* Lincoln and Citizens' Rights in Civil War Missouri: Balancing Freedom and Security by Dennis K. Boman (LSU Pr).
* Kansas's War: The Civil War in Documents by Pearl T. Ponce (Ohio U. Pr).
* The Civil War in Mississippi: Major Campaigns and Battles by Michael B. Ballard (UP of Mississippi).
