The problem with the black levels on the LED sets though is that they only really reach the same levels as the likes of the high end Panasonics and of course the Pioneers using the auto dimming feature, so in order to get the really deep black levels you need to be watching something dark, the only time they will reach Kuro levels is if there's nothing on screen at all. In normal viewing the Samsung LED edgelit sets have very similar or even the same black levels as the regular LCD sets from Samsung, these black levels are very good, and are around the same area as the entry level Panasonics and LG plasmas which is down to the LCD improvement in this area, but the only LED sets which can produce plasma beating black levels in normal viewing are the LED backlit sets like the Samsung 9 series, we'll see if they match in picture quality as well when the new ones are out.
And the 200Hz systems potetially remove (at best) or drastically reduce the problem of motion blurring and resolution loss, but these systems aren't perfect and you get the artefacts and 'soap effect' as a side effect which, to get the same (at best) as a plasma, seems to be a bit of a downside to be honest. These systems are also recommended to be turned off when watching anything but sport (because of the artefacts and soap effects) so you still get blurring and other motion issues on movies and regular TV.
LCDs are improving faster than plasmas, no doubt there, and the gaps are being closed all the time, but I personally think that the only hope for LCD to reach plasma level at the moment is in LED backlit sets, all LCDs are generally better in bright lighting and some people do prefer the LCD picture, but at the moment they're too flawed for my liking (viewing angles, lack of shadow detail, motion etc...) and I don't think they'll fully catch up to plasma before OLED comes along in a big way, sometime around 2015 I'm told
