I'd wait but then I've never been an early adopter. In this case my reasons to wait and see are as follows
2. Does DTS have a similar technology in the works? I once had a receiver that could play Dolby Digital but not the DTS equivalent. It made almost every movie purchase a challenge. Never again.
Christmas Eve I purchased a new receiver and speakers but upon reading about the new DTS:X format. I returned the unopened boxes as I waited for CES before opening. DTS:X will need a hardware upgrade so I will wait till the fall when the new Onkyo receivers will be out.
DTS:X I suspect will be popular on BR as DTS is now.
