He knows but I doubt he will tell.
What's your guess. One more round of NA for the 992.1 GT3 and RS??

73 Carrera RS 2.7 Carbon Fiber replica (1,890 lbs), 06 EVO9 with track mods. Former: 16 Cayman GT4, 73 911S, Two 951S's, 996 C2, 993 C2, 98 Ferrari 550, 79 635CS
I'm hoping that the 992 GT3 or at least the 992.2GT3 will go NA+hybrid like the 918, so NA will be back and Turbo's left for their traditional application of the 911 Turbo and not for "cheating" the emissions tests on other variants. Turbo is not the future, its really not more fuel efficient in a sportscar, only if you are driving Miss Daisy like in current emissions tests, but if you actually step on the throttle it burns through fuel just the same or even more than NA. To me it seems like a stop gap measure for emissions certification until better tech is available. With a hybrid you still get the NA, but also the electric instant push (no lag) and added performance, win-win, unlike the turbo. So hopefully that tech can trickle down to the 911 and have new types of NA's? fingers crossed, would really suck if my next 911 is turbocharged
I've read a technical paper written by Porsche engineers about the future of the Boxer engine. Here some interesting notes: "There are two different hybrid concepts – one with a large-volume, naturally aspirated engine, and the other with a downsized turbo engine. For the future, the focus must be on rightsizing and reducing complexity.
The topic of rightsizing needs to be reinterpreted for the future. Whereas we currently talk about rightsizing in terms of the “right degree of downsizing”, in the future a zero degree of turbocharging is also conceivable. The conflicting priorities of performance, emotionality, efficiency, weight and economy will see naturally aspirated engines be- come increasingly important again in combination with an electric drive, and they will form the basis for the design of the Porsche Boxer engine of the future – a slimmed- down engine with reduced complexity, for example through reduced variability in the valve drive and without turbocharging. This will reduce the vehicle weight and deliver emotional benefits thanks to high-speed capability and an attractive sound.
The disadvantages of combustion engine-powered driving, such as reduced low-end torque, can be compensated with the torque of the electric machine. Operation of the combustion engine in combination with the electric machine permits realisation of the required performance range – also in continuous operation. The possibility of load point shifting also creates fuel-saving potential."
