Wolfenstein 2: The New Colossus leakage is the latest games industry "oops!". A listing for the game has appeared on Amazon Germany, and has now been taken down again. 27 October 2017 was listed as the game's release date.
Wolfenstein: The New Order was heavily modified to suit censorship laws specific to Germany regarding the display of Nazi iconography and symbolism. It is a little strange that this latest leak would appear on Amazon Germany's web site.
A more official announcement might be coming our way during E3 in a few short days.
