It's no real surprise, but still nice to see. While rumours swirled about a Remastered version of The Last of Us on PS4 for a while, someone at Sony accidentally hit a switch early, as the game was listed - for a short while at least - on the PlayStation Network, as spotted by a NeoGaf user.
Likely pulled by the time you read this, the game was listed on the U.S side of the store with a digital download price of $59.99, (expect that number to change little in a conversion to pounds sterling). Not confirmed, but we'd expect the Remaster to come bundled with the DLC campaign, Left Behind.
No confirmation on the date yet though.
