Granted, I'm one of the writers, so ... fair warning. 
I think that's an honest issue. I'd say 2/3 of the book is strongly Scarred Lands. Organizations, how things work in SL, and so on.
However... I truly think there is applicability in many games. The prestige classes have notes on adapting them to other settings. There are items and feats which apply pretty much anywhere (except perhaps for things like Iron Fan, and that issue is gone over in the text)
The places where it is most setting-tied are the explanations of various organizations. But I think that content is useful. Some can be adapted directly, much of it may inspire organizing your own write-ups, and some can be tweaked.
So, for example, the War Colleges. You might easily have some kind of formalized warrior training in your setting. While the explanation of what each college is won't apply directly, you can say 'Ok, I have a college that focuses on infantry, another that focuses on mixing magic and fighting, ...' and then tweak the descriptions of the colleges to fit.
Another example is the barbarian and mercenary information. Both can be introduced into a wide variety of settings, I think.
Now, your experience may vary, but we had a fine appreciation of wanting to create something that had significance within the Scarred Lands, yet applicability to people in very different settings. We also wanted to try doing this in a _different_ way.
Not just prestige classes or random feats... the feats in this book really help bolster a feeling of War. Things like military training, and phalanx formation. Beyond formalized warfare, other ideas on what it is to be a warrior... like iron war fans, and atl-atls, and improvised weapons.
