Discreetly added the site of Amazon during the day of yesterday, Sleeping Dogs Defenitive Edition was indirectly confirmed for PlayStation 4 and Xbox One.
First announced for October 14, 2014, Amazon has since removed this date out for a more generic one of December 31.
On the listing, you can read that the open world action-adventure game has been "rebuilt specifically for next-generation consoles." It will also include all previously released DLC. Those who pre-order Sleeping Dogs: Definitive Edition before its release will receive a limited edition 28-pages art book included with their copy of the game.
You can now pre-order Sleeping Dogs Defenitive Edition for PlayStation 4 and Xbox One.
