And don't let's forget the wigs!

I'm definitely hoping for some good wig/facial hair based ancillaries.

Full-Blown Handlebar: "This man's facial hair is so elaborate that he can barely talk through it, but it certainly unmans any enemy unfortunate enough to face him in combat." -1 Command, Scares Enemies.

Absurdly Pretentious Hairpiece: "This man wears a wig large enough to stop a cannonball, but it looks ridiculous and is hardly practical on the march" +1 Hitpoints, -1 Morale, -25% Movement.

I'm also hoping for that most dreaded of military technologies, the sideburn, to be included as a researchable late game technology alongside the steamships and machine guns.
