Porsche made an epic error IMHO. How in God sake, they forgot about new regulations? And they did not prepare fast enough to handle it right?

Basically, there won't be any new cars from 15/07/18 till 15/01/19.

Yes, it will be pretty interesting period for Porsche. Only new 992 is ready for new regulations. All other models will be adjusted or maybe in case of some 991.2 models not adjusted at all and quietly fased out.
