Sad to see the demise of the Pioneers. The Elite models were truly the best of the best, and one of the few TVs that allow for professional-grade calibration without having to mess with the service menus.
Unfortunately, Pioneer could never figure out how to reduce the costs enough to make their PDP TVs profitable. To this day, my understanding is that their plant still can only cut one glass panel per sheet. Everybody else has been cutting multiple panels out of a single sheet for years.
With Pioneer's engineers now at Panasonic, the torch has been passed. I've been reading that Panasonic is looking to expand their presence with high-end installers, and expanding their product lineup accordingly.
With regard to CRT, I've always felt that they had the best picture quality and were equally adept with both HD and SD signals, something that cannot be said for any of the fixed pixel formats.
