multitouch exists right now (no new hardware needed) with video proof
 

Take a look: http://www.fuzemobility.com/multitou...e-or-software/
On a Windows device pressing two points leads to a key press of a point in between those points. That means for games you can create a virtual key in between the two points that is mapped as pressing both buttons. It works right now on your device. Just press down with a sharp object (like two styluses) on two points and the point in the middle will be 'pressed'. It's not very easy to do consistently but it does work.
This means games can be created for multitouch as long as virtual keys are mapped for dual key presses.

This unfortunately will never work as well as a true multitouch screen because of one main problem.

If you make your 2 points wider or narrower along the X or Y axis the virtual button doesnt change. Therefore movement in those 2 plane does not produce any change in state.

In the video he had 4 trigger points for his game, the reason he could not put the 4 triggers on all 4 corners is because it would cause the 2 diagonal virtual triggers to be on the same spot.

The more triggers you have the more virtual buttons, and as they get more dense so increase the virtual button error.

agreed - attached are two possible configurations of keys (including virtual keys)
