The G25 is neither top-of-the-line nor last year’s model. It is part of the new 2010 line and is a step below the top V25 series.

You’re correct on both parts… my mistake.  The G25 is indeed a 2010 model and their top non-3D model.  It also should NOT exhibit the black-level shift issue of the ‘08 and ‘09 models.  Thank you for catching my oversight!

Based on what I’ve heard, the new Panasonic’s may also exhibit the black level shift-just not as dramatically.
Panasonic has stated that the 2010 models increase base drive levels over time, but more gradually than the older models.
If the increased levels match the decrease in phosphor efficiency the black levels will remain the same, otherwise they will increase, but not as dramatically as before.
If you have different information I’d love to hear about it.

Updated. Thanks for the catches

Stephen,

I am interested in purchasing the new 2010 Panasonic G25 model.  You state that this model should not exhibit the black-level shift issue of the 2009 models.  Wondering what you are basing that on?  Just want to be sure that this model will not have the same issues as the 2009….

Thanks

Will,

I’ve talked with a couple of different Panasonic reps that have told me the black level shift should no longer be present.  It was not made clear whether “present” meant measurable or perceivable, but given the amount of press the problem has received, I can’t imagine it would be repeated to anywhere near the same degree as in the ‘08 and ‘09 models.
