Sam's Club is selling the Panasonic 51HX42 (non-widescreen) online for $1299 plus $140 shipping. This is the same TV that can be had for no less than $1800 from any other online retailer. I've been considering the Panasonic 53WX52 but this one has me wondering. This size 4:3 TV, has the same width as the 47" widescreen. Would I then get the same picture quality or would it have less resolution? The reason I ask is because Panasonic is advertising the same horizontal resolution (lines per picture height) for the whole line (widescreen or not). That would put the widescreen ones at 33% more horizontally resolvable lines (1.78/1.33). Is my statement correct? Is there a real gain in resolution going widescreen (dis-regarding the whole aspect ratio thing). One final question: Do new model TV prices tend to remain constant until the next model starts coming in or do the taper down gradually throughout the year? Much regards.
