^ Agreed on above points

I should have clarified that the final iteration of the 991.2 RS in certain markets has ITB and PF...

Finally, to emphasize the point further, how do you get people to trade up from the 992.1 GT3 or RS to the 992.2 GT3? A displacement bump (just like in the 997 and 991 generations) is an excellent way to spur demand, especially when the high-revving naturally aspirated engine becomes more and more a part of the unique selling proposition for the family of cars.

I wonder what redline the new race car will have?  And what about the road car(s) at a presumed 4.2L?
