Thank you for the heads up. This sounds promising but almost harks back to old school Osprey when they attempted to cover large and complex conflicts in a single volume. In this case, 48 pages to cover the armies of "Russia, Sweden, Denmark, Saxony, Prussia, Hanover, Holstein, Poland-Lithuania, Cossacks, Ottoman Turks, Moldavians, Wallachians & Tatars"...
I do like the various Osprey series but think it needs much more space to do it justice.
