As it says in the video Vehicles will play a big role in Ghosts, you can use tanks, choppers, and jets. such as in BF3 and ability to use parachutes in the game as an escape method when your vehicle is about to be destroyed or about to explode, or in maps where there are multiple buildings to get from a higher to lower point for a stealthier and quicker way.

The video also said that there will be different vehicles for an entrance to multiplayer games, instead of spawning in the beginning and having the count down, your dropped in the map by a plane or chopper or maybe out the back of a tank.

I'm not saying any of this is true or confirmed by infinity ward, these are all just rumors so please no hate mail about it.
