Anyone know when Pioneer or Panasonic will launch their next generation plasma screens? The current models have been around for about 18 months now! I know that Panasonic have stated that they will have plasmas brighter than CRT before the end of the year. It would be interesting to hear about any enhancements that are on the way. I have a Pioneer 503MXE and am thinking about a new plasma for the living room. I want to wait until the new models arrive.
