Yes, this is best case scenario. However, with the displacement limitations of the Flat-6, it's going to be difficult in coming years for purely NA car to keep pace with even the Carrera and Carrera S as they continue to get more boost (and maybe electric add-ons too). Even new GTS is not going to be slow with ~450hp and lots of torque...
The question you have to ask yourslef is what is really important in your sports car: is it having the fastest car or the most fun? Those two roads are starting to diverge.
Tires, suspension, gearing and weight are huge factors in performance besides just HP and torque. So there are many ways for future GT3 models to differentiate themselves.

It's just speculation.
The factory has never offered a flat 6 that displaced more than 4.0 liters, and that was relatively recent (later 997 race cars, 991 race cars; 997 and 991 GT3 RS 4.0 street cars).
It's difficult to construct a flat 6 that displaces more than 4.0 liters (pistons get too big), and AP said in the past that the factory could go no larger on the Mezger engine.
For the move from 3.6 to 3.8 with the 997 facelift, they increased the bores only (and added steel cylinder liners, as well). For the Mezger 4.0 they changed the crank.
Most aftermarket Mezger tuners (Sharkwerks, BBI, Leh Keen's car, which was built by Autometrics, etc.) will take a 3.6 to a 4.0 by boring, and then go to a 4.2 (BBI claims 4.25) with a crank.
It's not that they can do something that Porsche can't, it's just that the tuners are working in a very different, much smaller market. E.g., the Sharkwerks crank alone costs over $10K. Porsche has to sell to the masses.

with the above GT2RS 700HP and GT3RS 530HP windows
indeed the production capacity is filled
no room for either a GT2 and a GT3
maybe a converging GT3 a la 991.2 GTS but 500HP, suspensions, steering, wing?
