reginos:

Imagine the speed of the 4.0L if Porsche could fit a PDK gearbox. I hope all these anachronisms are corrected on the 991 GT models.

 It's true, you lose previous tenths of seconds in shifting times. A PDK gearbox is too heavy right now, and fragile in race mode, but I am sure they will work it out.

In the meantime, it's great fun shifting old school style, albeit slow.
