'GTA 5' itself has tons of hidden details, as well. In the past, fans have found other supposed messages from Rockstar devs, like a morse code message for someone named Dan in 'GTA,' hinting that a 'Bully' sequel could be on the way. Others thought it could mean that the title will be set in the future of the 2090s.Įven as many doubted the validity of the secret license plate message, others said that coming from Rockstar, it very well could be true. One commenter said that the plate could mean 'GTA 6' will come out in 2090, poking fun at the long wait fans have already had to endure. The plate only appeared briefly in the trailer, and some gamers weren't so convinced it meant anything special.
