All eyes are on the next iPhone, but Apple could also be working on a new Apple TV. The device could be announced next week, or maybe later this fall.

The anonymous Twitter account @never_released shared the codename of a new Apple TV — AppleTV11,1 or J305AP. They have been accurate when it comes to finding codenames of various unreleased Apple products in the past.
