Unsurprisingly, Grand Theft Auto 6 is in development.
What is surprising is that Rockstar once toyed around with the idea to make a game in their titular series set in Tokyo.
As reported by TechRadar, heads from Rockstar visited Tokyo to assess its potential for as the setting for a new entry in the series. This was around the time before Grand Theft Auto 3 and Vice City, and it is typical of the developers to visit a prospected area to gather information, take pictures, meet locals, and get a feel for the area. Unfortunately, Tokyo's streets and infrastructure were seen as problematic at the time and the project was scrapped.
Rockstar filed trademark for Grand Theft Auto: Tokyo in 2003 along with Grand Theft Auto: Bogota and Sin City. One would imagine that Rockstar would have a tough time making a game set outside of the United States today given how rooted the franchise is in the country, there are a ton of brands that are series staples that would have to change, but such an idea is not entirely impossible.
TechRadar's source also stated that Grand Theft Auto 6 is currently in development which is little surprise given that GTA 5 was release more than two years ago. Rockstar has continued to support Grand Theft Auto 5 with constant updates to its online component and released the long awaited heist update for the GTA Online last year, but there has been no other news about the long promised story DLC. Although Rockstar has been open about the development of the sixth installment of the popular franchise, they were quick to address that no setting has been decided.

With any luck we'll have more information about the future of Grand Theft Auto and all the other titles that reside under Take Two Interactive's publishing umbrella.
