It was in May/June that an insider reported that the black level rise was not fixed but that it would be reduced greatly in impact starting in sets manufactured in late May early June.
Then at the shootout we were told "not to worry" about rising blacks on the VT25 because by the time it impacted you then you would have moved on to a new top of the line panel.
Then, CNET around Sept/Oct right after the shootout that CNET published information on their longterm test panel and demonstrated that the MLL had doubled after 1500 or so hours of use.
At least that's my recollection.
Bottom line, even if insiders leak info, there's no way to know for certain until the sets accumulate hours.
Let's say that the black level rise is still there but it's been stretched out to 5,000 hours for the first bump? That means that in normal operation you would not see it for 3-4 yrs... and if no one at Panasonic discusses it, and no insider reports it, there's simply no way to know.
