Starting sometime in 2010, rumors emerged about Rockstar developing Grand Theft Auto V. Nothing was officially released on the game, but some leaked information suggests this game will have a setting in Los Santos (GTAs version of Los Angeles). Other information can only be guesses. For example: early this year, Rockstar registered five new domain names that could be intended for use in an in-game internet system (like the system seen in GTA IV with internet cafes allowing the player to access certain websites).

The domain names are:

CashForDeadDreams.com
SixFigureTemps.com
StopPayingYourMortgage.com
HammersteinFaust.com
LifeInvader.com

As with GTA IV, these domain names are meant to be somewhat humorous and may possibly parody real life businesses or programs (the best example being the CashForDeadDreams.com domain possibly parodying Cash4Gold or other similar businesses).

According to unnamed sources, the game is very likely to be released in 2012, but could also possibly be delayed until 2013. Since Rockstar usually likes to keep their poker face going and only show their cards when they're closer to their release date, it's mostly speculation on what the game has to offer and when it may or may not be released. More information will be posted as it becomes available.
