[Franklin's Trailer]
I. The gang that Franklin is interacting with is wearing green, the infamous colours of the Grove Street gang that CJ belonged to in San Andreas
II. Additionally, some of the rival gangs spotted are wearing purple coloured clothes - suggesting a reference to the Ballas, the primary rival gang of Grove Street in San Andreas
III. Franklin's clothing changes throughout the trailer, suggesting customisable clothing will once again be returning
IV. During the video, a couple of first person sections are present; one inside a police helicopter and another on the bonnet of a car during the chase
[Michael's Trailer]
I. Michael's son is spotted playing videogames and talking on a headset, suggesting that the leaked casted call from many months ago was correct
II. Yoga has been said to be an activity you can undertake when playing as Michael, and this trailer shows someone taking part in the exercise
III. The possibility of destructible environments is teased during a section where a large truck smashes through a wall
IV. Michael is seen primarily in the wealthier Vinewood area, the richer part of Los Santos and designed to represent Beverly Hills
[Trevor's Trailer]
I. Trevor is seen primarily in the dusty outback of Los Santos. This is a little more interesting than the other two and their locations since this area was already discussed by Rockstar, but it hadn't been seen before
II. This could just be part of a cut-scene, but Trevor is spotted lying on his back on the wing of a plane shooting a rifle. This could suggest elements of Max Payne 3's prone shooting has carried over into the game
III. Trevor also kicks someone out of a helicopter while its in the air. It's not clear how he got to be in the air while he did it, but this might suggest that this new action can be carried out by anyone playing the game
IV. The TV is spotted showing a Sprunk advert towards the end of Trevor's trailer. It's not necessarily confirmation of anything, but that could mean that the ability to watch TV will return
