According to a listing on ShopTo (since pulled, but spotted and captured by Gamrreview), Sleeping Dogs is getting the HD treatment and will be released on PS4 and Xbox One later this year. As you can see from the image below, a November release is mentioned, although that's also potentially a placeholder.
Sleeping Dogs ended up being a surprise when it released in 2012 (a nice surprise at that), and with another game in the Sleeping Dogs universe in development - Triad Wars - also in development, a HD update of the original isn't out of the realms of plausibility. More details if and when we have them.
