According to a new memo from Apple informed service providers that it has AppleCare-related changes planned for Tuesday, December 8 at approximately 5:30 a.m. Pacific Time. Specifically, Apple has advised technicians to prepare for new product SKUs, new/updated product descriptions, and new/updated product pricing.
There have been countless rumors about Apple's item tracking AirTags, AirPods-branded over-ear headphones, and a new Apple TV with a gaming controller, but it is unclear if any of these products are ready to launch in 2020.
Given that AppleCare changes are expected, it is likely that any product(s) announced next Tuesday would have AppleCare+ coverage available, so we could be looking at new hardware. However, in the interest of tempering expectations, it is possible that the announcement could be for a minor accessory, or that no announcement transpires at all.
