Incidentally, STAFF(if that is your real name), I finally received word from Pioneer's customer service as to when they'll be rolling out the DTS:X firmware upgrades for their upper-tier Elite Receivers. They answered thusly:
"Thank you for contacting Pioneer Home Entertainment.
To answer your question.
We apologize for the delay and thank you for your patience.
The firmware enabling DTS:X in Pioneer AVRs is in the final stages of development. We continue to work closely with DTS and its manufacturing partners and intend to make an official announcement of a release date sometime in the late summer of 2016."
Just thought I'd throw that out there since no one else has any info on Pioneer's DTS:X plans.
