I am very curious about this too. I have (2) VT25s (54" and 58") and I too want to finally buy a new 65" Panasonic plasma like I should have done before. I don't even want to mess with the ST60 from all of the lag issues that I've read about. I personally think the VT25 has a perfect picture...even after 2-3 years. The problem is when I read the reviews of the new TV, they always say that the picture is dimmer or lighter or more reflective or not reflective, etc. Those are just general statements that compare that year's TVs....but doesn't necessarily compare to what you or I have or watch on a daily basis. I keep reading that the VT60 is dim and more reflective, but I have no idea how if its more reflective or dimmer than my VT25.
We almost need to find someone with both of them to compare them. Or even better, if the guys at CNET or other sites would list every spec of every TV in a grid so we can side by side compare them. Hopefully there will be someone out there that has both that can help us out.
