[Marcus Moore] “my general impression is that most iPhone users are on a 2-3 year upgrade cycle anyways”
Given the standard turnover every two years under contract it could take 3 years at least depending on where people are in their contract cycle. Keep in mind many people are still signing up with iPhone 5c and 5s so they’d have to turnover as well. Tablets might be even longer. They’ve still been selling iPad 2 up ’till this point.
[Marcus Moore] “Moving iTunes content to h.265 will undeniably be a process that takes years”
Yes it will for sure.
Apple’s iPhone 6, iPhone 6 Plus use H.265 codec for FaceTime over cellular

H.265 technology, also known as High Efficiency Video Coding (HEVC), for encoding and decoding FaceTime video calls over cellular.
…
Exactly how Apple is implementing H.265 is unknown at this time, but considering the feature is restricted to the iPhone 6 and iPhone 6 Plus, some speculate the new A8 SoC incorporates a specialized encoder/decoder module not present in older handsets. Further, Fleming points out that while Macs have the processing power to run software-based H.265 encoder/decoder solutions, portables usually require hardware integration.
Currently that would only iPhone 6 to iPhone 6 series. Phone companies would be supporting because it’s lower data demands than H.264.
BTW although Macs have the processing power to do this, I don’t doubt it will eventually get hardware assets as well and that will be a big impetus for people to upgrade Macs if you need to deliver H.265 professionally. Two years from now we may be doing a lot more H.265 encoding and that may well make the current MacPros very long in the tooth.
