Much is still needed from 'brick builders' and 'minifig customizers' alike. There's a website dedicated to organizing the build, as well as a forum thread on BrickArms.
Many historical details and reference pics can be found on the site. There are four factions of troops needed for the build: Wehrmacht, British Commonwealth, US Army, and French Resistance. You must be registered for BrickCon in order to contribute.
I didn't see any mention that contributors would be eligible for goodies from BrickArms, or discounts at their store. If anyone has more details, please let us know!
