The Van and the Pilatus will never happen. 9K won't go single engine or turbine. The EV-55 has never flown so expect that to take years for approval.
Of the 3 the EV-55 is most likely. The 402 has a few years left and they will be stretched if the EV-55 is the choice frame and the Chech's give us a deal on the price.
Also those turbine's will come off and be replaced with a TCM Jet-A burning diesel engine (which they claim they have engineered and will produce enough power). They don't want turbines because of how many cycles we put on our planes.
