With Rockstar Games keeping quiet about the inevitableGrand Theft Auto 6, fans have been scouringGrand Theft Auto 5for any possible clues about when the next game in the critically-acclaimed series will launch. The latest theory claims that theGrand Theft Auto 6release date has been inGTA 5since the game’s launch back in 2013, and while that seems unlikely, the evidence is still somewhat compelling.

Grand Theft Auto 5players have once again taken note of some doors at the Los Santos International Airport, thinking the numbers on them reveal theGTA 6release date. This isn’t the first time this theory has been brought up, but a tweet by GTA 6 News has given it renewed attention. Basically, the airport doors have three sets of numbers on them: 2013, 2014, and 2021. 2013 is the yearGrand Theft Auto 5launched, whereas 2014 is the yearGTA 5was ported to PlayStation 4 and Xbox One. Fans have theorized that this means 2021 will be the yearGTA 6will launch.

Since video game companies typically don’t plan release dates out so far in advance, the more likely scenario is that this is just a coincidence. However, it is worth pointing out that these are the only numbers on the airport doors. Considering this, perhaps this was done on purpose, with the developers simply guessing that theGrand Theft Auto 6release date would be in 2021.

As it stands, it’s difficult to say when exactly theGrand Theft Auto 6release date is.Industry insiders are divided on how far alongGTA 6is in development, with some thinking that the game is still in the very early stages of production, and others believing that it’s well on its way to being finished. So depending on who is right, aGTA 6release date in 2021 is certainly within the realm of possibility.

IfGrand Theft Auto 6does launch in 2021, it will be interesting to see how much truth there’s been to the many rumors that have been circulating about the game. Rumors and supposed “leaks” have made all kinds of claims aboutGrand Theft Auto 6, claiming to reveal details about theGTA 6mapand the game’s protagonists.

UntilRockstar Gamesitself decides to reveal more, fans will continue coming up with their own theories about theGTA 6release date. Hopefully official information comes sooner rather than later so this nonstop rumor and speculation can be laid to rest.
