Japan seems to get all the really awesome game bundles. The most recent example is a special "Treasure Box" edition for the upcoming Hyrule Warriors, which includes a Triforce clock, a treasure chest, and a scarf.
While I'm not a scarf fan (not just because they can be dangerous), the Triforce clock and treasure chest (which apparently features sound effects!) are both incredibly neat. Either one of those makes for an incredible pre-order item but both? No one collector's edition should have all that awesome!
Of course, Japan isn't the only country to get special Zelda swag. The UK had a collectors' edition for the incredible Legend of Zelda: A Link Between Worlds which included a musical treasure chest that could store 3DS cartridges.
