Probably not a good move to tell the same company to copy their own product!! As far as I know there will be turbo-versions of all engines - 2- and 3-rotor, gas and Jet-A. Jet-A will be only a few lbs heavier due to the heavier injection system. Power-levels are the same. The highest at this time will be the turbo-3 rotor at 360 hp.
