From windows stand point, same for Mac/IOS, there probably isn't enough demand for them to go beyond what they are offering now. The HTPC users don't seem to be making noise/demands on the newest codec, the vast majority seem to be quite satisfy with even the regular 5.1. I hope they would eventually offer everything the latest 15.x.6 that some of the best popular AVPs can do, but then they might just kill the AVR/AVP market.
