Well, you can definitely say this much about Rockstar: they know how to build expectation for a game! All it took was one trailer to send a whole army of GTA fans into a speculative frenzy about what new features will be in GTA 5. Will there be crazier weapons? Will old characters come back? Will there be a female character?
Well, one thing is for sure… nobody really knows. However, there have been leaks here and there that gave us fans more insight into the game's developments and new features.
Some fans have been speculating that popular characters from previous releases might come back in GTA 5. There have been rumors that the Grove Street Gang might make a return and that characters such as Tony Cipriani and CJ might return to our console screens.
Rumors of the return of the Grove Street Gang (from GTA: San Andreas) have been encouraged by the fact that you can spot references to the gang in "The Lost and The Damned" (an expansion pack for GTA 4). However, as one member of GTAForums said, previous versions of GTA were set in a previous universe, so it's unlikely that old characters will make a comeback. You may see them on ads around the city or hear about them on the radio, but the chances of actual characters coming back on screen are pretty slim.

However, there is no official indication either way as to whether Rockstar will choose to forsake its previous formula and bring those much loved characters from Grand Theft Auto San Andreas back onto the scene. It is not out of the realms of possibility — especially since San Andreas was the most critically acclaimed game of the series and given that GTA 5 is set to take place in the state that shares the name.
There has also been much speculation as to what the main character's gender will be. As you may already know, the gaming industry is trying to target female demographics more aggressively. It has been said that 48% of current gamers are women, and this would be the perfect opportunity to put a female in the lead role. However, if the trailer is any indication, this is unlikely to happen since we can only see a male protagonist.
Dozens of videos have surfaced on Youtube that highlight some of the new features we could see in GTA 5. Once such clip, embedded below, points out a few features that could be part of the upcoming release. These may include:
