Samsung has never demonstrated that they (or other Korean companies) will release products that have been "modified" to boost test results. It does make you wonder if they released the 8500 knowing that they would have to come back later with fixes that raised the black levels. The Korean's have a long history of poor corporate ethics, I believe Hyundai announced today that it had overstated its mileage figures after doing it along with Kia in 2012. Samsung does a great job innovating by using others designs and tech in their products. Not saying it was a conspiracy, but with the track record you have to wonder.
As much as I would like to add a plasma in another room this year - I may refrain given what seems to be evolving with the 8500. Maybe the jet engine fans on the VT/ZT are a blessing - cooler panels longer panel life
Only time will tell.
