Amazon.com has sample cover art and a blurb for the upcoming Galaxy at War source book for the Star Wars: Saga Edition Role-Playing Game. From the blurb, it looks like this book plans to do for war and soldiers what Scum and Villainy did for thievery and scoundrels. And based on what Wizards' own web site has to say, it appears the game will also offer options and rules for the Star Wars Miniatures Game as well.
The Amazon.com product description says:
New rules and character options for war campaigns.
Warfare is a common theme throughout the Star Wars saga. From the Clone Wars to the Galactic Civil War to the Sith-Imperial War, soldiers have their work cut out for them. This supplement gives players and Gamemasters everything they need to run games or play characters in a war-torn galaxy. This book provides rules for military units as well as new character options, new gear and starships, and a host of adventure hooks and campaign seeds that can be used to inject military flavor into campaigns of all eras.
I don't know -- this book seems like a repackaging of the rules we got in The Clone Wars Campaign Guide. Admittedly, those mass combat rules were quite cool, but did we need a rehash? The part that sounds most appealing to me are the adventure hooks and campaign seeds; those were some of the best parts of Scum and Villainy. With the Mandalorian Wars and Jedi Civil War looming large in my own Star Wars campaign having a bunch of ready-to-run scenarios could be very handy.
Thanks to @Lumrunner on Twitter, I discovered that Wizards of the Coast also has a preview up for Galaxy at War. What's interesting about their write-up is this quote: "The perfect gaming supplement to Star Wars Miniatures: Galaxy at War". It also mentions guides for creating fortresses and battle stations and a bunch of new content from The Clone Wars animated series.
