Don't bet on future technology. It's expected as of now that the future will be LED, OLED, AMOLED, but no one can say for sure that LCD will go. The thing is such technology is controlled by the manufacturers and they will not let go of an old technology and replace it with a newer technology until and unless they've made a profit from the existing technology and money recouped on its R&D. For instance Intel already has technology that it will release in 2020, but it's not going to release it now. Not until it makes its profit from dual core and quad core. Even replacement for Blu-Ray is here, but after the expensive war between HD-DVD and Blu-Ray all want to make profits first before even thinking about introducing newer/better/replacement technology. That's how the industry works. It's not always the better products and technologies that sell or run. It's a closed/controlled market and with CRTs being phased out all will be forced to go for LCD or plasma since nothing else is available.
My recommendation is if you're happy with your CRT then yeah wait. Or else pick something cheap but with great quality like the PV8. As things stand today in a couple of years LED and its various acronyms are supposed to take over and LCD and plasma phased out, but no one knows except the manufacturers and they do control everything.
BTW, I have a plasma, an LCD and 3 CRTs at home and all of my main TV watching including the IPL is done on a 29" CRT. It absolutely kicks everyone/everything else (i.e. LCDs and plasmas) in terms of PQ. So if you're happy with CRT then stay put. You will have more and better options in 2 years.
