German Amazon had the release date for the Xbox One, PC and PS4 listed as 14th November 2014 according to this source. This is not the first time as a release date for the game on the three platforms appears. It is the same date as anither retailer had.
The information was quickly removed from Amazon’s website. Rockstar has not confirmed any release date for the PC, PS4 and Xbox One ports, but still says it will come in autumn.
