Could somebody please tell me why MW3 Hardened Edition is so large?

[Gemini-Phoenix]

As the title says, could somebody please tell me why the Modern Warfare 3 Hardened Edition comes in such a large box, when all it contains is a SteelBook, notepad, code card, and a few DLC leaflets?

Did it really constitute such a large and quite frankly nondescript box?

The outer box measures approximately h9" x w6.5" x d3.5", when the contents would fit into a box less than half that depth! Why is this edition not of equal size to other CE's such as Gears Of War 1 & 2 or Mass Effect 1 & 2?

It just seems a bit wasteful and pointless if you ask me. There's absolutely no legitimate reason for the box to be this size, so why is it?
