The 1/72 market is generally geared toward traditional topics of British interest (Hastings, Hundred Years' War, Waterloo, WWII), although thanks to companies such as Strelets and Zvezda some Russo-Ukrainian topics have become more popular in the past two decades (Great Northern War anyone?). The 1/32 scale is shaded very heavily toward USA themes such as the North American theatre of the Seven Years' War, Texas Rebellion (The Alamo), Battle of the Little Bighorn, and of course WWII. The two scales overlap sometimes, but perhaps not as often as expected.
