Next GTA??

General Information:
There are 3 playable main characters. Their names are Trevor, Franklin and Michael.
You can switch between them at any point when not on a mission. When you switch, the camera zooms out into the sky and then back down to the character you switched to.
Each one has its own personality, motivations and skillset. When you're not controlling them, their lifes continue and you may be surprised to see what situations they find themselves in when you switch back.
Each character has own story arc
Several complex missions focussed on heists in style of "Three Leaf Clover" from GTAIV.
Some characters from GTAIV will make an appearance in V. Niko won't be one of them.
During research, Rockstar took over a quarter million photos this time!
Census information and vehicle sales data were used as a guide to depict the game world.

Properties will not return from San Andreas but loads of other features that you can buy will be included so that you can use the money that you may have.

Features:
You can flip off other characters in the game, and see interesting results dependent on who you're flipping off.
Vehicle physics have been updated. "The cars hold to the ground a bit better". It now feels more like a racing game, compared to GTA IV where they felt "big and boatlike".
After a hiatus in GTAIV, Ammu-Nation is back!
A lot of new side activities, including yoga, jet sking, base-jumping, tennis and golfing on a full golf course!
Rockstar felt that dating wouldn't fit in this game and have stripped this feature.
Bowling, Strip Clubs, Live comedy, Internet cafes and in-game TV make a return.
Mobile phone will return, but friends won't be calling as often as they did in GTAIV. It will be more streamlined and used for things like emails and Internet browsing.
Random character encounters throughout the map, much akin to those in GTAIV - but this time there's a greater variety and they're fully motion captured.
Dynamic missions, similar to Red Dead's "Random World Events" make a return. Examples include characters with broken down cars, a hitch hiker, or two parked cars with dead bodies around them - which you can investigate to initiate dynamic missions.
Dynamic "state machines" were coded in the game, allowing non-playable characters to go about their daily lifes. For example, you may see gardeners and cleaners waiting at the bus stop in the morning, and then find them tending the gardens and houses in the game's fictional Beverly Hills later on in the day.
