UPDATE 08/08/2014: Square Enix has confirmed this week's leak of Sleeping Dogs: Definitive Edition.
The game launches on PC, PlayStation 4 and Xbox One on 10th October 2014.
24 pieces of Sleeping Dogs DLC have been integrated into the experience, including the story-extending episode Year of the Snake and the horror-themed add-on Nightmare In North Point.
"It was an exciting opportunity for the original development team to be able revisit a game we're so passionate about," said Dan Sochan, senior producer at developer United Front Games.
"We're giving old and new fans a lot reasons to pick up the game, as we've gone beyond just increasing resolution and running at 1080p. We listened to the fans: we tuned gameplay, we added to the ambiance of Hong Kong, increased audio fidelity and pushed the visuals further than we could on the previous generation of consoles."

ORIGINAL STORY 06/08/2014: A listing for Sleeping Dogs: Definitive Edition on PS4 and Xbox One has appeared on Amazon US with a projected release date of 14th October.
This is the second time a listing for a next-gen version of Sleeping Dogs has been spotted as we saw a page for it at ShopTo back in June - although that estimated a 21st November release date.
The Amazon listing appears more thorough as it even has an ad for a Limited Edition pre-order bonus that comes with a 28 page art book.
According to Amazon, it will cost a full $59.99 and will include all the game's DLC.
We've contacted publisher Square Enix to verify this information and we'll report if we hear anything substantial.
