While there are few big releases coming up in 2012, there are a handful of games that still remain well guarded by publishers and developers before they make any big developments or revealing announcements. These games have had very less exposure till date and fans all over believe that something big is heading their way.

Here are five games that have well hidden by the developers and publishers:

South Park: The Game (Sequel) - As per the latest reports, the plan of a sequel to the previous South Park game surfaced only last year, and, till now, we have only seen a handful of screenshots from the game.

South Park television series creators Trey Parker and Matt Stone have always been known for finishing projects in a hurry, but successfully, and now it is being thought that their commitments towards the TV series could hinder the work on the game, and hence no progress has been made as far as the game is concerned.

Moreover, developers Obsidian has been famous for their delays in projects. So, if the issues are settled, the game could arrive as soon as in the summer of 2012 or later after 2013.

The Last Guardian – The Last Guardian was first mentioned in 2009 and till now an official release date for the game is pending.

Brief screenshots, small gameplay demos and a few trailers are all that the game has to offer till date. The game has been delayed for years now and although some expected a little about the game at last year's E3 expo, nothing is certain.

Few believe that after creator Fumito Ueda recently departed Sony, the project fell through. But if that is the scene, then we might never see the arrival of the game. What we really do know thus far is that The Last Guardian is a third-person perspective game that will combine action-adventure and puzzle elements.

The player will control the unarmed yet-to-be-named boy who can run, jump, climb and perform other actions similar to the gameplay in Ico and Shadow of the Colossus.

Grand Theft Auto V – The possibility of the next eagerly anticipated Grand Theft Auto game surfaced in October 2011.

An official trailer of the game has already arrived with an intriguing new logo. It is, at this point, safe to say (probably) that the game will not arrive in the next 12 months. This is primarily because developers Rockstar might want to focus more on the upcoming Max Payne 3 at this point.

Depending on GTA IV's debut trailer in March 2007 which was just a year before the actual game's release, one could assume that GTA V could arrive next spring. Nonetheless, Rockstar has always been known for surprising its fans and, hence, anything can happen.

Prey 2 –  Prey 2 was first announced back in August 2006, then in March 2008 and then again in March 2011.

The developers and the publishers have, nonetheless, managed to put forward a live-action announcement trailer, and a few screenshots.

A gameplay trailer that was still awaited for the game, finally made its mark at the E3. The game is said to be enormous and lot more was expected from publishers Bethesda about the game.

Few believe that the game will finally arrive sometime this summer, or in October or November.

We do know that Prey 2 will run on the id Tech 4 engine and will focus on the story of U.S. Marshal Killian Samuels, who starts the game on a passenger flight which suddenly crashes onto the Sphere (the crash is shown in the original Prey).

Borderlands 2 – Borderlands 2, which was revealed last year in August 2011, has come up with a teaser trailer and a hands-off demo that was shown at Gamescom and PAX last year till now.

It can be assumed that with new releases from Gearbox like Aliens: Colonial Marines and Brothers in Arms: Furious 4, the developers will not take the chance of releasing Borderlands 2 so early.

The game, as per reports, is currently under development by Gearbox Software and takes place five years after the events of Borderlands when the four vault hunters exposed the secrets of the Eridian Vault.

Returning gameplay features from the first game will include the unique, cartoon-esque cel-shading graphic style, 3-branch skill trees, class-mods, and four-player online cooperative modes.
