It sounds kind of cool on paper  like Natal but I havent seen much of it yet. I wanna be prepared but definetly dont know what to expect. 

So there is no working link to the video :(

Just type in in youtube geometrywars natal

If you are controlling an image on screen using the movement of your hands then that's gesture based. The fact that the same effect can be achieved using 2 analog sticks, or that your hands basically map to analog stick equivalents means it's only the most simple gesturing that is needed. If you move your hand for the purposes of conveying a meaningful signal then that's a gesture.

I can't go back and check now, but I thought he was also using a bit of finger waggle for something too, but maybe not.

Well I am going to have to disagree with your definition of a gesture based system. A gesture based system is one that uses a series of contiguous frames to correlate to a known "gesture" which then executes an in game action. This game needs only 1 frame to determine everything. If we were to use your definition of gesturing, that would include almost every game ever made. The only differences being how the movement is detected, be that an analog stick. or a button. This is far too wide for my liking.

Usually when someone refers to "gesture controls" they're referring to a proxy motion that stands in for a standard button press. Essentially an unnecessary input scheme beyond being more satisfying to execute, like swinging a controller to represent a clubbing strike instead of just pressing a button.

Unfortunately it also refers to any sort of wild spastic flailing that is interpreted by the software as a series of inputs, not much different from rapid button mashing.

IMO, once you start using those gestures to accurately (key word) replace the directional input of an analog (other keyword, as in velocity sensitive) stick, is when things start getting a bit more intricate and go beyond the whole "proxy" motion for button presses. Motion velocity of the player should directly control the speed of the corresponding action on screen.

But with analog stick replacement controls for something like Geometry Wars, technically all one should have to do is move their index fingers or thumbs up/down, left/right since the game itself only records motion input on the X and Y axis. You shouldn't have to pantomime with elaborate hand movements, just little subtle finger movements.

can we have an official natal thread. thank you and good night lol.

Very good to see it in development.

It don't work.
