The XBOX ONE does the decoding and passed the uncompressed audio to the receiver like BlueJays said. So you do get DTS HD decoding, but the problem comes into play when you want a receiver to DECODE the audio, and not just play back the already decoded sound from the XBOX ONE. The decoder in the XBONE and a receiver are not created equal though. Most will prefer the receiver doing the decoding, but it doesn't mean that the XBONE doesn't support DTS HD.
Last week here in the US you could upgrade from to a XBOX ONE and get $175 if you traded in your 360 at Best Buy (half off of a $350 bundle). This week it is $150 for the 360 at GameStop and you can use that towards an XBONE bundle starting at $350, OR a PS4. With the announcement earlier this week about the XBONE adding backwards compatibility with games from the 360 (rolling out this fall), some people may want to upgrade to the XBONE. It was kind of funny how Sony was totally shocked by the announcement. They were completely blindsided by it. Again, I just mention the upgrade deal for anyone following this thread and want to get the latest XBOX of PlayStation.
