Responding to questions on its official website, a Rockstar source said that the developers are working hard on the title and that more details will be revealed in a "few months time".
"Right now, we are very hard at work on the game and are excited as well to show and tell you more as development progresses - expect that we'll be talking much more about GTAV starting at some point in a few months' time."
Rockstar also reiterated the fact that Grand Theft Auto V will be its "largest and most ambitious" game to date.
"Grand Theft Auto V is set in the city of Los Santos and its surrounding hills, countryside and beaches - and it will be the largest and most ambitious open world game we've ever created…"
Grand Theft Auto V was announced last October, with the debut trailer going live a week later.
Release dates or platforms are yet to be announced, although some analysts have predicted a summer launch for the title.
The game's lead character is thought to be a man named Albert De Silva, played by Ned Luke.
