I feel like this would be a good move for a future design of the system. They would have to continue to make sure that it wasn't multitouch because that would mean enhanced capabilities and fragmenting the fanbase if developers take advantage in future games. However I would like it because after playing with it a little it did seem a little unresponsive compared to my phone.
