Also, a God of War Collector's Edition was listed by German Retailer Spielegrotte on May 25th, but has since been removed. Includes the following, costs €199,99:
BD game (BD probably means Bluray Disc)
9" statue of Kratos & Atreus battling 2 Helwalkers
Two carved sons toys figurines
Steelbook case
Exclusive Lithograph print
Cloth game world map
Digital soundtrack
Exclusive dynamic theme
Shield pack containing 3 in-game shields
Release date was January 15th, but that sounds unlikely since that's a Monday. Q1 2018 sounds like a safe bet though.
