As we reported earlier this year (in October actually). Thief will be NetEnt’s first game in 2013.
It will go live in January and NetEnt has just released a preview video of the gameplay.
What they say about the game:
The setting of Thief™ changes throughout the entire game, taking players from the rainy street of the main game to the upper levels of a hallway and a vault found in the Free Spins modes. Players experience a roller coaster of feelings, creating anticipation of what’s to come with every spin of the reels.
