Out Of Ashes (Boxed Set)

I was randomly visiting the Warner Music Germany site and saw that a box set version of Out Of Ashes is about to be released on November 20th in Germany.
The website gives away no further info about the content of this boxed set, neither does any other site as of now.
It sounds pretty promising but what could it be? A box with a DVD, or an extra CD with the acoustic tracks, or a t-shirt?

More info about it should be coming out soon, hopefully before the release. Until that, discuss!
