Target, GameFly, and Best Buy are all listing the game as coming out June 20, 2014. However, Amazon lists the game's release date as December 31, 2014.
The June date may be a placeholder or just a guess from someone entering in release dates for the game, but it's interesting that it matches across three major retailers. We've reached out to the stores and Sony for confirmation, and we'll update this story when we have more details.
The date is notable both for falling on a Friday and coming the week after this year's E3.
