Apple is also thought to be preparing to widen its push into original content provision and to provide a range of "skinny bundles" of content. This focus on content means the company may soon be in position to leverage 4K support, subject to industry support, standards support, and -- crucially -- broadband speed.

We can't be certain when Apple will leap to support 4K in Apple TV. Bloomberg speculated the standard may see support introduced in a new Apple TV model, but those big problems need to be resolved before this truly makes a difference to customers. However, it is arguable that once Apple does deliver on 4K it may drive an explosion in demand for 4K content and compatible 4K television receivers.
