Old Plasma Vs Newer Plasma

Most likely yes yo would see an improvement with either TV....Int eh end though only your eyes can trully tell you that...

Better buy it all depends on price and persoanl preference...

You can try to find the GT or the VT, but most likely you will see stock starting to dwindle as stores make room for the 2013 models.....

I just went from a 46pz85u, to a 60gt50.

No comparison!! Deeper blacks, more accurate color, brighter picture, improved audio quality
Bluetooth audio, 3D, web access, on and on.

Have you noticed a difference in heat output as well? I have 2 50PZ85Us and the TV in the bedroom heats up the room considerably. I looked up the power consumption of my unit and it's 690W. The newer TVs consume less than half of that so I would assume there would be a difference in heat production.

Thanks!

We have 3 Pan plasmas: 42", 50", and 60" - Smallest to Largest, but also Oldest to Newest.

"Heat output per square inch of panel area" has undoubtedly declined (presumably = Improved) with each newer panel - but (AS A GUESS) the sheer size differential between the 60" and (at least) the 42" offsets the improved efficiency.

One thing to keep in mind is HOW the power consumption is determined. For example:on the two older panels, "Standard Mode" is BRIGHTER than Cinema, whereas with the newer set (a 60ST50) "Standard" is the Least Bright picture mode (given all are at their Default settings).

IF Panasonic measured all three panels at Default Standard Mode Settings, the "Improved Efficiency" of the 60" would likely be overstated for MOST users.
That is, WE run the 60" in Cinema most of the time, moving to Custom for some viewing (particularly for day time / bright room viewing - & notably for Sports broadcasts).
The various "picture settings" posts on the board suggest that MOST users also do NOT routinely use Standard, thus foregoing Energy Efficiency in favor of Improved PQ.

I upgraded from a 2008 Panasonic 46PZ80U to a 2012 50ST50.
The black levels were noticeable improved and much brighter picture as well plus the new set is much thinner and lighter so easier to install.
I also like the additional features including smart TV internet functions and 3D.
Its getting late in the cycle to buy the 2012 models though however, they are in short supply and not as many good price deals as a few months back.
The 2013 model ST60 won't be a huge change however.
