According to the latest report from Bloomberg, Apple is developing a new product to diversify HomePod products. The product will combine Apple TV and HomePod speakers, and may add a camera that allows users to use FaceTime through Apple TV.
In March of this year, Apple stopped its HomePod production line, and it has been more than 3 years since the last update of Apple TV, so Apple also has a great chance to launch a new version of Apple TV.
Apple merged the HomePod and Apple TV development teams in 2020, and unified the basic software that runs on these two devices. This is an early hint that Apple may finally integrate the two product lines.
