Sorry. I wasn't clear.This is an idiotic argument. They get engineering samples precisely so that they can design for chips that "don't exist yet". They get design documents precisely so that they can design for chips that "don't exist yet".
While you are correct to an extent, there is still a lengthy "Qualification" process by Apple, where they make sure the PRODUCTION versions of the chip(s) ALL pass both Engineering QA, plus it takes a bit for the chip mfg. (Intel, in this case) to start providing large-quantities of a just-released chip.
Now, that we can (finally) get Engineering-Approved PRODUCTION Components, we have to get "Production" involved. Production Quantities have to be Ordered, Received, Qualified (yes, again! At least the first Order Received will be), Production-Samples of EVERY VARIANT of the Product have to be Built, Gone-Over with a Fine-Toothed-Comb both by Hardware and Software Engineering, Packaging and Production people. And then, any ISSUES that crop-up along the way have to be addressed, one-by-one, signoff-by-signoff, until the big Green "Go" Palm-button is pressed, and the Production actually starts to flow...
Oh wait. Somewhere along the line, "Agency Approval" Testing has to be done for EACH VARIANT of the Product(s) Involved. That ALONE can take MONTHS.
All these things add weeks and weeks and WEEKS to the process; and all this AFTER Intel's "Press Release" goes out.
To companies the size of Apple and Intel, Engineering Samples of a component and Production Units of a PRODUCT that USES that component are quite a ways apart.
Now multiply that "fun" by EACH VARIANT of the component that is used, and EACH VARIANT of the Product(s) they are used in.
I have several DECADES of experience Designing and Developing the hardware and software for over a dozen Industrial Control and Measurement Products. I have been "in" on this process (albeit on a smaller scale than an "Apple" would be) several times.
