Hello I am glad the Z2 is coming out because it reassures that my Z1 is not abandonware, but I wanted to ask what is new in the Z2 besides a new sensor?

Is the only difference really just the sensor?

I was hoping there might be a new Joystick mode that allows to also move the mouse around the mouse mat. It might be used as an alternative to the feet that allow for side-tilting only. Currently the Joystick-mode mouse feet for the z1 are stationary and completely block out the sensor.
