Not really, rather sony added the ability to select convert DTS into Dolby 5.1 IF the blu-ray has the 5.1 track on it (I'm not sure if all Blu-Rays have the 5.1 track or not). You'll still need something to convert the 5.1 into DH.
Regarding your last post, IF youre willing to give up chat altogether, then you could choose a TB DSS1/2 or Creative Recon, and maybe budget for an amp along the way. All of the Headphones in your list will benefit from the secondary amp, some more than others. I can only comment on the Q's and DT990pro250. If you're mainly using them for gaming then the Q's are a better choice with a bigger soundstage, and ample yet not overpowering bass, while the 990 is better for movies with loads of bass which is perfect for action movies.
