"Grand Theft Auto 6" release date is reportedly being pushed back further as Rockstar Games will be releasing "Red Dead Redemption 2" this year between the end of September and December. This has naturally caused a huge amount of disappointment among fans who now understand that the "GTA6" game has been delayed for an indefinite period. Currently, there are speculations surfacing that "GTA 6" is also on its way.

It looks like the production of "Red Dead Redemption" is the reason why "GTA 6" will not be produced and released anytime soon. Developers of Rockstar Games are said to want to devote their attention to the former, given that the first title of the western-themed series was released in 2010.

According to YouTuber Itz Frolickz an Easter Egg was spotted in "GTA 5" has given rise to the speculation that the "GTA 6" will be released not before 2021. The YouTuber believes that the release date of "Grand Theft Auto 6" has already been teased in "GTA 5." A weird door numbering that featured in one of the current game's airports has dropped the clue. When players visit the particular airport and look closely, they will find two doors with the number 2013 and 2021. This is very strange considering the fact that door numbers always follow a definite pattern.

To add fuel to the speculation, the other doors in the airport do not have any numbering; only those two doors are numbered. This has led fans to believe that "GTA 6" will be released in 2021 as according to speculation "GTA 5" was released in 2013. While this theory is the most believed right now, another theory states a 2020 release date for "GTA 6." As per an earlier report by Tech Radar, Rockstar Games, after three years of "GTA Online," was ready to do "red Dead Redemption 2."

However, the Rockstar Games has announced that there won't be any "GTA 6" now as it is solely focusing on making "Red Dead Redemption 2" a success. If only the "Grand Theft Auto" series is taken into consideration, then it points out at a 2018 release of "Grand Theft Auto 6." "GTA: San Andreas" was released in 2004, while "GTA 4" released in 2008. "Grand Theft Auto 5" was released in 2013 after a five-year gap. Hence, it could be 2018/2019.
