I don't think H.265 is ready for the mainstream. Last I checked it was still pretty clunky. Besides which, as of yet there are no Apple devices that can yet record 4K out-of-the-box. On the other hand, I don't expect this will be a product that Apple will update regularly, so there may be some future-proofing if it's on an 18-24(+) month refresh cycle. I'm looking forward to this, along with the 6S Plus I'm hoping to get.
