Let's talk Collectors Editions

I'm a sucker for collectors editions, only if they've got really good stuff in them (no statues). And it's been awhile since CoD had one.

They way they hyped up your online character being able to join a division, I imagine a collectors edition would include a (plastic) wearable M1 helmet with an assortment of division stickers you can place on the sides.

What would you like to see in a collectors edition?
