Well, someone has to do it...
Do you consider a business model similar to "Command Ops 2" ?
Basically the "demo" would be the full game but with only a few showcase scenarios.
Then you would sell "scenario packs" or "modules".
Such a modul would then be "Tobruk 1941" or "France 1940", containing campaigns, scenarios, the needed artwork and the OOB's.
This way you can keep the "core" (the demo) always up to date and people will always be able to play their modules with the most up-to-date "core" engine.
Also, i know Tiller probably hates Steam...what about a Steam release ?
More and More Hardcore Wargames can be found on Steam !
-Command: Modern Air / Naval Operations
-Gary Grigsby's War in the East
-Decisive Campaigns: Barbarossa
-Flashpoint Campaigns: Red Storm
-Close Combat
-All the Ageod games like "To End All Wars"
And soon "Command Ops 2":
Steam Greenlight

The old argument that the developers would loose money seems invalid (if it was ever valid).
Most of these games are even more "hardcore" then PzB, still they sell on Steam well enough that more and more wargame developers consider Steam as a platform !
Also you dont have to fear "tons of bad reviews" by casual players, just look at the reviews for monster games like Gary Grigsby's War in the East !
I think, releasing the free demo (the core game) on Steam to get players interested and then selling DLC's (modules/scenario packs) sounds like a great idea to get much, much more sales !
Steam is the biggest platform by far and even if you will need to share a few $ with Steam, your possible customer base will explode !
But then again, i think Mr. Tiller will sadly never agree to this, he loves his little and well hidden shop in the corner of the internet.
