It looks like the next Sleeping Dogs DLC has been outed according to a trophy/achievement list and a teaser trailer.

The DLC is apparently called The Year of the Snake (not shown), and you can take a look at the trophies associated with it according to Exophase.

A purported teaser trailer has also popped up on YouTube. We'll contact Square Enix for a comment and update if anything substantial occurs.
