I'm holding off on getting anything resembling a new TV until a cavalcade of the new LED LCD TVs come out.
Not only will all the light-box based LCDs (7 series and older) become cheaper, the LED LCD will be so amazing that you would question why you would buy an older one anyway.

Likely, yesterday's release of the new LE series is already reflecting in the price of older LCDs
