The bottom line is that Porsche and its shareholders don't give a damn about car enthusiasts. If they do there would be no Cayenne and Turbo Cabriolets.

By the way, who were the Porsche’s intended customers for the GT2’s??? Wayne Gretsky?

I was under the impression that the cup car had little to do with homologation and that Porsche used GT3s and GT3 RSs (street cars) to homologate the recent GT racing cars. The most recent homologation car was the GT3 RS (street car) to let Porsche use the GT3RSR race car, but the previous GT3s were used to the homogate the GT3R and GT3RS race cars respectively. So if they want to have a 997 GT3 race car they need a 997 GT3 street car that has enough race car goodies so that the real race car will benefit from them.

the 996 GT3 RS homologation is good for 5 years after production ceased, so by the time there is a homologation problem, the 998 will be in production.
There is NO need to homologate the 997 Cup car. Given PAG's habit of building these in batches of 200 or so, it might not be too big a stretch to say that it begets itself in homologation terms. As soon as the car goes racing under FIA-ish rules, think Spa or Daytona, either the rules are changed or the PCCB brakes have to be replaced by iron ones, to say nothing of the frankly dumb rules banning centre lock wheels, or have these been binned at long last?
When Cup cars race in the VLN (Long Distance Championship at the Nuerburgring), or similar series, they are given a class of their own, with minimal required changes to the original specification.
A big and expensive change, that is a long time coming, is the switch to an FIA approved fuel cell, only required in some events to date.

Here is a quote from RC at rennteam. He is in Germany and he always has the most accurate information.
"1. PSM seems to be confirmed
2. Power is still rumoured to be 381 HP like on the "old" GT3 but I expect at least 400 HP
3. GT3 RS is expected to have more power, no PSM and maybe a sequential shifting system after it is introduced on the 997 Turbo.
We still don't have ANY info on the used engine for the GT3. The GT3 RS seems to get the "classic" M64 engine block but it may be possible that the GT3 gets a M97 derivate.
Again: we have no official confirmation on the engine used.
GT3 rs will probably be the old 3.6 motor. GT3 will be 3.8 with PSM. Ugly.

IMO they will continue to run the 996 GT3RSR till they need to homologate a 998 or Cayman based car. Lets not forget that they will also have the prototype car to focus on.

Unfortunately I don't know. I brought my hotlap timer, but not the transponder. I figured someone else would have one, but apparently not. I'm sure it's pretty quick. Me and the other GT3 were lapping at about the same pace (both in stock trim on stock tires). He had just bought his, and he came from a C2 cab with MPS cup tires. He thought he was already faster in the GT3, and I think he said he used to do 2.04 or 2.06 in the cab. So, I'm not sure what that makes, but somewhere around 2 minutes I guess. I don't have any other reference to compare to, so I'm not sure how fast that would be--

WOW! I hope I wasn't wrong about the GT3 engine:

All sources indicated a 3.6 dry sump with 400 HP.
