Some time ago the pack-back was shown. Now I get a mail about the Nano-edition and a totally different back is shown.
The first back was wayyyy better looking. The new one does not even come close.

See the picture. The left bag is how it was shown before and the right bag is the new one. Nano-editions are being bought by your biggest fan, you can't suddenly come with a totally different (not so good looking) bag (not to normal customers and absolutely not to the real fans). It does not even look like the first bag! And I’m guessing the new one is not bullet-proof or something so it really is all about the looks. And they pay enough, it cost about 3 times the normal addition (€130) that will probably be the most expensive game/edition ever.
Still love Crytec but changing the bag is really a mistake if they would go for the ‘new’ bag.
