 Not to be the devil's advocate, but being a Ham and also a Home Theater
enthusiast, Plasma has some very distinct advantages over LCD tech at this
point in time, so I seriously doubt they are just going to vanish overnight.
I myself even have some Plasma based sets, but I think with the better
quality models you do get better builds as would be expected.

 That said, plasma has MUCH wider viewing angles than LCD's while maintaining
color accuracy and brightness levels.   Yes that has improved in more modern
LCD sets, but with a Plasma set you can damn have a true 180 degree viewing
experience is desired.    Also screen refresh rates are much faster on
Plasma, why they don't suffer from the motion blur that is so common on LCD.
Last by not least, black levels, and LED dimming for LCD backlighting has
improved LCD tech a great deal, but you still can't beat the black levels of
a good plasma (yes there are cheaper ones that don't perform as well), plus
in general you will find the brightness transitions are also better as shown
in many tests.  

 So though there are some great LCD sets on the market, when it comes to
eeking out the best possible image quality, and theater movie accuracy, LCD
still can't beat Plasma, so until that changes, I don't think your going to
see them vanish from the marketplace...
