It has now been confirmed that 2K Czech has been closed by 2K Games.
2K Games gave the following statement to VideoGamer:
We have relocated and consolidated our 2K Czech team from our Prague facility to centralize resources in our location in Brno. Additionally, we are transferring some development resources from Prague and Brno to 2K headquarters in Novato, CA.
This transition will both strengthen the integration of the 2K Czech team with our award winning development teams, and better align cross-functional business practices. As part of this realignment, we are adjusting our staffing levels, resulting in the elimination of some positions.
2K Czech were responsible for making Mafia 2 as well as Top Spin 4 just to name a few. Now that some of the staff will now relocate to California, it’s unknown what game they may be working on. It was rumored they were developing Mafia 3.
