Depends on the volume of the dealer. My dealer is smaller and thinks he is only getting two. I would develop a back up plan, if it was me. I'm #2 on the list so I think I am good. Once I get a build commission number, I can relax.

Strut rear suspension? As opposed to what on the GT3? Pushrods?

The correction is there because all piston speeds are not created equal. If you go purely by piston speed a small piston and a large piston would "score" the same if they have the same stroke and RPM, despite the fact that a big piston is going to be heavier and thus create more stress.

To calculate "mean piston speed" in meters per second you multiply (stroke in meters x rpm x 2 / 60 seconds). Based on this a car like the Audi RS5 is the top of the street car heap: 92.8mm stroke and 8400 rpm gives 26.0 m/s piston speed vs the 991 RS's lower 23.9 m/s. But the RS5 has small 84.5mm pistons while the 991 RS has fat 102mm ones. "Corrected piston speed" allows for this by multiplying mean piston speed by (square-root (bore /stroke)). This is a better measure of relative stress, and it give the RS5 24.8 vs the 991 RS's 26.7.

Milti-link. The 911 uses struts up front, while the Cayman uses struts all around. Multi-link (or double wishbones) is found on the rear of the new 911s and all the Porsche supercars, 959, CGT, 918. And the front of the RSR race car, where it's reportedly worth about a second a lap...

Chatted with my dealer this afternoon. Right now they are saying US deliveries will start arriving in July/August. I guess each on is kind of speculating until Porsche finally announced it

FWIW, I don't give a hoot about bragging rights so I'm happy to admit right now to the fact that the RS will be faster than a GT3. But just to keep it real, $45K will buy a lot of "little crumbs".

It seems a lower stroke but higher bore would be much much easier to rev faster since the mean piston speed would easily be changed. In any case, it seems a higher revving engine, despite the great advertising it could spawn, would not be worth the problems it would eventually have.

Now I inderstand the real value of the Mezger, and how you described it as modular and the DFI as tuned to its potential.
Yes, larger bore, shorter stroke (over-square), all else equal equates to a rev happy engine.

Maybe I missed it, but I didn't hear anything about the rear fenders being different than the GT3 or turbo, in which case they are steel.
