The references, pointed out by Mark Gurman on Twitter, have likely been added as Apple took notice to the rumor mill’s response to leaked product codes, and decided to have a bit of fun with the Apple news community as a result.
In particular, the references include “iPad10,1,” iPhone11,1,” “AppleTV8,3,” and more, comically suggesting products many generations in the future.
The real reason for the inclusion of these fake items, however, is likely to make it difficult to detect new additions, which can provide clues as to which devices Apple may be testing their software on.
