Take-Two Interactive, parent company of publisher 2K Games, has seemingly registered domains for Mafia 3.

It is worth noting that domain registrations are relatively easy to fake. The ones attached to Mafia 3 include servers located at RockstarGames.com, in addition to Take2Games.com, which is somewhat unusual.

Additionally, this may also be a case of a publisher securing domains for one of its intellectual properties for future-proofing purposes.

Previous rumours, however, have suggested Mafia 3 is in production.

In March 2012, it was reported that Mafia 2 developer 2K Czech working on a third entry in the series. At the time, the studio had supposedly entered full development on Mafia 3 following a year of pre-production work.

More recently, in January 2015, voice actor Rick Pasqualone, who played Mafia 2 protagonist Vito Scaletta, teased that a new Mafia game may be announced soon.

"Might have some Mafia news very soon," he said to one fan. To another, who bluntly said, "make Mafia 3," Pasqualone replied: "Might have some exciting news very soon."

Later that year, another report said Mafia 3 was in development at 2K Czech for Xbox One and PlayStation 4, and was going to be a launch title for those platforms. However, the game reportedly suffered from production issues, and those plans were apparently abandoned.

2K Games parent company Take-Two Interactive said in March 2013 that it has an "extensive pipeline" of unannounced games in development.

The next major video game event is GamesCom, which takes place in August. It may be that Mafia 3 appears there.
