This could be one of the earliest confirmations of a next-generation title.
According to Eurogamer , 2K Czech is currently cranking away on Mafia III , which is in development for "the PlayStation 4 and next Xbox."
Interestingly enough, it was originally scheduled to be a launch title for next-gen consoles, but this is currently "unlikely" as they've suffered a few cutbacks in recent years. They're staffing up now, though, as they're seeking 13 new employees to help them on the project; they want artists, programmers, designers, etc. Last we heard of 2K Czech is that they were supposedly assisting with Rockstar's Grand Theft Auto V , but Rockstar quickly debunked that rumor.
However, much like GTA, Mafia is an open-world title that has a heavy focus on crime…or in this case, specifically trenchcoat mafia crime. If you're bored, you might want to check out the decent Mafia II .
