Trailers do contain gameplay footage. They just use a special detached camera. A lot of what we saw in the first trailer was gameplay - not cutscenes.
I can't wait to play as loving Jack Nicholson.
From GTAV.netInformation:
Underwater world (with underwater caves) and diving equipment confirmed.
Side-missions similar to Taxi, Ambulance and Vigilante will be back but "probably not identical to the ones in previous GTAs" because they wouldn't fit in with the 3 main character personalities, but the "three will have odd jobs to do".
Trevor will be the skilled helicopter pilot, Franklin the skilled driver and sniper, Michael the "smooth operator", skilled and versatile.
Franklin is looking for a mentor and he finds one in Mike after they meet during one of Franklin's repo man jobs.
Trevor is inspired by the typical GTA player that only roams around the game creating havoc, death and destruction.
Mission types will vary among "big and small events , explosive, infiltration, super spectacular, family issues, invasion, hostage recovery, heists and robberies. Plus classic GTA missions but updated and improved."
Cover mechanics have been greatly improved and cover will be very important in the gameplay.
About the economy, Dan Houser says: "You will be able to spend money to buy interesting and fun things like expensive toys. We are still working on the economy but it will be a strong element in the game and players will be eager to make money to spend money. Something along the lines of "I went through all of this to make all this money and now I'm going to spend it on this crazy item."
Dynamic music during missions (similar to games like L.A. Noire)
No co-op for single player missions, but co-op modes will be featured in multiplayer.
Big focus on multiplayer with a lot of content to keep players busy.
The song Radar Love was heard playing on the in-game radio.
Alamo Sea is the name of the Salton Sea like area.
Radial menu to select the 3 protagonists.
Switching in missions partially scripted - meaning, at times character switching will happen automatically.
In final part of a mission in the demo, the player can decide which character to use.
There are multiple different endings in the storyline which depend on the choices you made throughout the game.
The storyline takes around 25 hours to complete.
Map open from beginning, with the exception of some protected areas.
A certain amount of money will be needed to gain access to some missions.
