According to several retailers (Best Buy, Amazon, GameStop) Mafia 3 may be releasing on April 26.
An image below was sent by a Best Buy store to IGN, and shows a pre-order card for the game along with a sticker for an April 26 release date. This lines up with a listing on GameStop, which also lists April 26, 2016. Even more so, Online retailer Amazon also shows this date as well.
Mafia III is the next entry in 2K’s open-world crime series. The game will take place in 1968 New Orleans. This time 2K Czech is developing the game along with Hangar 13. Mafia II was a fantastic open-world game, and told a riveting story of friendship and betrayal.
These sort of leaks happen all the time and we will update this story when there’s official confirmation on the game’s release date. If this is indeed the release date of Mafia III you’ll notice that it’s the same date as Naughty Dog’s Uncharted 4: A Thief’s End. Hopefully Mafia III won’t get buried.
