I totally agree,
I was playing the demo earlier today, I got in a helicopter, flew wayyy up high, then bailed out.
I was flying through the air as my empty helicopter was doing the same.
Then I attempted to grapling hook the falling helicopter as we both spiraled back down to earth, (just like in Goldeneye when he is flying after the plane), I almost had it but had to pull the parachute just before I hit the ground.
As I did this, the helicopter erupted into a large explosion beneath my feet, I came spiraling out of the explosion attached to my parachute only to be presented with a huge firefight of enemies below.
The game has completely blown my mind, can't wait to buy it.
