In a word, no. Plasma is still the closest display to the standards set by direct view CRT. I too have high hopes on the OLED technology and hope that my current tv holds out till the OLED tv's are priced low enough for me to afford.
I have looked at the different LED, LCD and DLP displays and always migrate back to the plasma. The sad news is that (rumor only at this point) Panasonic and possibly Sony have plans to stop making TV's. I have only heard that from one source, a dealer, and haven't researched it. Maybe some else here can chime in with more valid evidence of this actually happening. In advance I appologize to anyone offended by my plasma preference, I mean no discredit to your buying decision. All is my opinion based upon what I see. YMMV
