I believe so. My latest Osprey email newsletter lists one of the army list books as an upcoming release in with the standard fare.
In fact, according to the email you should be able to get it (and all other Ospreys) for 30% off until 26 March by entering 8EGG in the promotional code box. Shipping is free to the US, UK, and Canada if you order three or more books. The only restriction seems to be that they must be in stock at the time of ordering.
