UPDATE: Ubisoft has announced the PlayStation 3 and PlayStation 4 versions of Watch Dogs include exclusive DLC.
Those who buy either of the PlayStation versions get access to 60 minutes of additional gameplay which can be downloaded via the PlayStation Network.
"We're really excited for the launch of Watch Dogs on both PS3 and PS4 and are confident that it will prove to be one of the standout games of 2014, said Michael Pattison, vice president of Third Party Relations at Sony Computer Entertainment Europe.
It's a unique and visionary game and we believe that the exclusive content available via PSN will not only excite gamers, but showcase how PlayStation is a preferred destination for Watch Dogs."
Meanwhile, Ubisoft has confirmed the recently-announced 27th May release date for Watch Dogs applies to the PC, PS3, PS4, Xbox 360 and Xbox One versions. The Wii U version will release "at a later date".
ORIGINAL STORY: Open world cyber thriller Watch Dogs launches on 27th May, a leaked trailer for the game has revealed.
The video popped up on Xbox.com (Ubisoft has now released the trailer through its official YouTube channel - it's below) this afternoon ahead of an expected official announcement by publisher Ubisoft at 5pm. At the end of the trailer the release date is revealed.
The new date means that Watch Dogs has seen an extra six months of development time after its delay last year. Initially due to arrive on 19th November - and as a launch title for PS4 and Xbox One - Ubisoft pushed the game into 2014 with just weeks to go before release.
