During its official announcement at Pax East 2019, one major detail about Borderlands 3 wasn't confirmed, and that is its release date. Yet it appears that this release date could have actually been hidden in plain sight in the game's official reveal trailer. Because the Borderlands 3 tease contained several hidden messages, including morse code, braille, and a SHiFT code, hiding the release date in the official trailer is by no means a stretch of the imagination.
According to Redditor Zottelpanda, the Borderlands 3 release date is October 1, 2o19. Before moving forward, it's worth mentioning that this is simply speculation, so this news should be taken with a healthy dose of salt. At 1:39 in the official trailer, there is a big white building in the background. At 1:51, a 10 can be seen on this building, and prior to that, at 1:40, a 01 can be seen on one of the skyscrapers.
The question may be why is this being taken to mean October 1 instead of January 10, but there are actually several reasons backing up this theory. First, October 2019 will be an anniversary for the launch of the first Borderlands back in 2009, meaning Borderlands 3 could be giving a nod toward the original, which is receiving a Borderlands Game of the Year edition Remaster on April 3.
Another supporting fact for this theory is that October 1 is a Tuesday, which is a common day of release. In other words, everything adds up to suggest that this Borderlands 3 theory has weight, with more details set to come on April 3 as well. Considering the anniversary correlation and the release of the original remaster on April 3, an announcement of this release date would not be out of the question.
Until then, however, we have to wait and see, as the ball is in Gearbox's court. With walking guns, multiple planets, and the interesting pair of baddies known as the Calypso Twins, it seems safe to say that the official Borderlands 3 trailer excited many fans of the franchise.
Borderlands 3 is in development for PC, PS4, and Xbox One.
