No release date or artwork information yet.
But on a German forum, where I am a member as well, Phil from Turbine (the company that will produce it) confirmed that it will be released as a futurepak, not a mediabook.
So could a moderator/admin please move it to the appropriate section, please? Thanks.
Oh yeah, this will be the world premiere of the Unrated version on BluRay.
