I'm sure there will be many 6.0 OS versions for non-touch, each specific to the device for which it was written. There are only 2 touch devices from RIM, so I'm guessing they chose the storm to demo the 6.0 as the bigger screen can show off more features. I'm sure it won't take long for the hybrid makers to take every 6.0 build they can find and build some nice hybrids for current devices.
