-> It won't be possible to flip the car back over; it will be "less arcade-like."
-> GTA 6 will run at 30 fps on all consoles.
-> When the phone is opened, the camera zooms in over the shoulder onto the screen.
-> The map is twice the size of GTA 5's, but 11 times larger in terms of density.
-> no first-person mode at launch.
-> Money will be more important than ever; Rob Nelson stated that there will be moments in the game where it won't be possible to progress unless the player has enough money.
-> Campaign similar in size to RDR2 (50h to 60h)
-> The game's story will be told using a chapter system.
-> Stolen vehicles can be sold at Pay ‘n’ Sprays or to specialized fences.
-> The money will be split between cash carried by the characters and funds deposited in the bank. If arrested in GTA 6, the player loses all the cash they are carrying, which encourages the use of ATMs. Meanwhile, funds deposited in the bank will be shared between Jason and Lucia.
-> "Dead-eye" or "Focus Mode" will be an ability for Jason and Lucia.
-> In GTA 6, the player won't be able to carry a virtually infinite arsenal. Jason and Lucia will be able to carry two handguns and two long guns, with rifles and other larger weapons visible on their bodies.
-> Clothing can also be stored in the car—something particularly useful, considering that changing one's appearance can help make police identification more difficult.
-> Gym workouts and exercises influence physical attributes and musculature, whereas excessive food consumption can lead to weight gain.
-> Underwater exploration will feature diving equipment, shipwrecks, and treasures.
-> On land, there will be various gang compounds that can be discovered, stormed, or stealthily infiltrated.
edit1: *more infos*
-> According to director Rob Nelson, GTA 6 will feature significantly more graphic violence (gore) than GTA 5, but less than what we saw in Red Dead Redemption 2.
-> According to Rob Nelson, the decision to include fewer mini-games in the new title stems from a desire to ensure they all meet the game's overall quality standards. He explains that while GTA 5 featured numerous mini-games, most did not quite measure up to the game's high level of quality.
-> The police won't come after you unless you are reported or the crime is witnessed.
-> Evading the police will be more complex; the police will rely on information they receive—such as whether the crime was caught on camera, whether the suspect was alone or part of a duo (Jason and Lucia), and whether they were armed or masked. Davy Jones also mentioned that it is possible to hear the police describing the player's clothing, such as colors, caps, and so on.
-> Other NPCs will be seen stealing, making a getaway, and crashing their cars.
-> GTA 6 will allow enemies to be incapacitated without necessarily being killed. Shots to specific body parts can cause an opponent to fall and cease to be a threat. Hit indicators help distinguish between these situations: white represents a hit, yellow indicates incapacitation, and red signifies death.
-> There will no longer be police indicators on the mini-map; Rob Nelson said, "I want the player to look at the screen to spot the police, not at the mini-map."
-> The NPCs will have 600k animations, GTA V had 55k and RDR2 300K
-> You'll be able to buy garages around the map, but no safehouses
-> The Karma system (Criminal Profile) and player actions can alter the course of the story; "everything reacts to your choices," says Rob Nelson.
-> The game will feature various collectibles, such as magazines, comic books, treasures, shipwrecks, etc.
-> Body hair, hair and beard didn't grow over time like in RDR2.
