I've been interested in purchasing a Panasonic TH-50PX500U. I can't seem to find one at a reasonable price. I talked to Panasonic and they said that "this model has been discontinued". In fact it appears that all of their 42" and above models have been discontinued. I'm assuming that they are starting work on newer models. They couldn't say. Is this a good time to purchase or should I wait for the newer version? Does anyone know what new features might be available on the newer models that would be worth the wait? Any ideas on pricing? Sounds like the new models will be available in late March.
