Update: Square Enix has confirmed these details in a press release, with the official title as Hitman HD: Trilogy.
If Hitman: Absolution has made you curious to go back and take on Agent 47's greatest hits, you're just in luck. A retail listing, along with sets of achievements and trophies, indicate that an HD collection is on its way early next year.
The Amazon listing (via Joystiq) for the "Hitman Trilogy HD" features its own convincing box art. The bundle promises remastered versions of Silent Assassin, Contracts, and Blood Money, similar to a retail leak from over the summer. It sets the release date for January 29, 2013, at a price of $39.99.
