Apple TV 4 will be presented on September 9 together with iPhone 6S and iPhone 6S Plus, and by then I already found out that Apple Lossless Audio CODEC (ALAC), would have prepared a completely new interface for his product, and a concept tries to show us how it could look.
The latest rumors about Apple TV 4 suggests the fact that it is to be controlled for the most part and using the personal assistant Siri, and this concept confirms everything, including a major change for the way the entire content is presented on televisions.
Of course, no one knows if the interface will really look like this, but the chances are very high, so if you see something similar in a week, you shouldn't be very surprised.
