I'm betting that's real though, as they've already announced the digital special edition on Steam that includes a "DLC Loot Bag", which contains extra money, guns, and a few masks in-game. I'm hoping that we'll really get a physical mask (especially if it's Wolf's!). Not sure why the mask would be latex though, as the game masks are more like a hockey mask, sort of.
Anyway, the nice thing about Amazon is that you can preorder and since it won't charge you until it ships, you can always decide later down the road to cancel the order. That's what I normally do.
