Early in 2013, it was said that the first amendment to h.265 was expected to be completed by the end of 2013, but I have not seen any official announcement out of ITU that it as been approved yet.

The range extensions amendment was completed in April but the ITU is going to wait until July to create the second version of HEVC so they can also add the scalable extensions amendment. Sony has made comments about the Main 12 profile being used in the near future. I don't know though if that means anything of if they were just stating an opinion.
