Seems as if they've already changed the cover for Den Frieden verlieren (and the model), unless the cover version in this new catalogue
(an update of an older one from a few months back) is an older version:
EDIT TO ADD:
I Have asked about this version on the CC forum, and the reply was that this is a "newer alternative version", so I guess both are in the running. For "internal reasons" they aren't able to provide a bigger (better) version of this draft at the moment.
In other news, they have posted character drafts for Soleta
and Zak Kebron
on their facebook page, as they plan to use such pics for the backcovers of the NF novels, and have said that they also plan to have new covers for the New Frontier books.
