Mafia 3 is in development for Xbox 720 (codename Durango) and PlayStation 4.
That's according to the 2K insiders close to Eurogamer.cz, who claim the next chapter in the gangster series will release at the end of 2013.
The 2K Czech sequel was originally planned for Xbox 360 and PS3, the report claims, but the studio decided to switch development over to next-gen consoles last summer.
The Mafia II dev is also rumoured to be contributing to the development of Grand Theft Auto V in the animation area.
2K Games has yet to comment on the rumour.
