We just upgraded our 10 year old 50inch plazma TVs to some new 55 inch Sony 4K LED TVs and ..............................WOW! What a next jump up in technology. These are amazing better in picture quality, color brightness, and clarity. I would highly recommend looking into the new 4K TVs if you are thinking about a new television. Are plazmas were definitely starting to degrade. The heat that was generated by the plazmas were huge in comparison to the ones. The new TVs don't even get warm. The new ones don't hardly have a frame around them. We love the new. Anyone else make the upgrade yet?
