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.
Either way, Wolfenstein 2: The New Colossus was listed on the site for a short while, before being taken down again, but a diligent NeoGAF user has made sure that screen-caps survived the incident.
The listing shows the games release date to be 27 October 2017. ZeniMax and Bethesda don't seem to be immune to the recent industry wide leakage.
A more official announcement might be coming our way during E3 in a few short days.
