It's not the first time Apple chooses to do so. Apple has previously unveiled new products with press releases outside of the core iPhone lineup. And there aren't any rumors or teasers coming out of Apple regarding an October event.
Gurman believes that by the end of this year, the tech giant will introduce the M2 and M2 Pro-powered Mac mini, 14-inch and 16-inch MacBook Pros with M2 Pro and M2 Max chips and possibly 11-inch and 12.9-inch iPad Pros with vanilla M2 chips. Even if Apple introduces new Mac Pros next month, deliveries will likely start next year.
The announcement of a second-generation AirPods Max seems to be less likely, but a refreshed Apple TV with A14 chip and more RAM seems to be on the cards.
