I totally agree Doc, about the low quality of the compressed streaming and also the desire to see it (and hear it!) in true 1080p glory! I've watched it a few times on Netflix mainly to help bump up the numbers for the streaming totals and other stats that Disney is most likely looking at to gauge interest. And actually on my end, the Netflix stream was better than the terribly compressed U-Verse service I have. And plus, it was fun watching a second and third time around! TRON LIVES!!
Back in February, I purchased the 82-inch Mitsubishi DLP 3DTV (upgraded from the 60-inch) that they aren't making anymore. I got a great deal on it, and I have to say, even with the compressed signal, TRON: Uprising still looked pretty good! My setup is nowhere near the setup you have, but you and I share the same anticipation of seeing it on Blu-ray!
Come on, Disney! I know you want our money, so release it already! GET BUSY!! LOL!
