It sounds like Apple wants their next TV to appeal more to gamers.
9 to 5 Mac are reporting that "sources with knowledge of the product" believe that Apple " will actively compete for TV gamers with updated hardware, software, and peripherals" with their latest iteration of Apple TV.
Earlier reports have suggested that the remote for the Apple TV 4 will feature physical buttons alongside the touchscreen, and there's some suggestion that it may be able to operate similarly to a Wii remote as well.
We can expect to learn more about this on September 9, during Apple's planned event. Whether Apple plans to seriously challenge the home console market in the same way they have disrupted the handheld gaming market remains to be seen.
