Is H.265 coming to the A7s to allow internal 4K recording?

A visitor of the CES show shared  the following info:

Speaking to Sony rep at CES, he indicated H.265 may be coming to A7x platform. In theory, this could allow A7S to output 4K (H.265) to the SD card due to the lower bitrate possibility. Would eliminate the requirement for external HDMI recorder for 4K, as long as you are OK with the H.265 compression.

The Samsung NX1 uses the H.265 codec for 4K recording. But I really don’t know if Sony will do this. There may be overheating issue when recording 4K on the A7s. But if Sony would find a way to add internal 4K recording I would certainly be happy!
