SED - The SED is "officially" dead, but Canon is still playing around with the technology. Don't rule out another appearance down the road. Presently, economics are working against it ever appearing in a consumer TVs.
KURO Plasma - Test-drive a Samsung 8000-series plasma and you will see right away that Samsung adopted the front-surface polarizing screen that Pioneer used to get their deep blacks. It has no effect on side-to-side viewing angles, but vertical viewing angles are very narrow - go outside 35 - 40 degrees and you will see a marked drop-off in brightness. Also, blacks on this TV are extremely low, maybe not as low as Panasonic, but around .09 - .1 nits. I'll have a full review on my Web site (
www.hdtvexpert.com) later this month.
Sharp 108-inch LCD - Sharp made it clear this was not going to be a commercial product, just a technology demo to show how large a cut of glass they could make from their older fabs. You may have noticed that the "mine's bigger than yours" contests between Samsung, LG, Sharp, and Panasonic stopped a couple of years ago - TV manufacturers are more concerned with sustaining profit margins on existing screen sizes these days. In any event, Sharp has a 70-inch LCD TV coming to market and Samsung showed a 75-inch glass cut that will be commercialized. Look for the pro AV market to have these first, as they are not cheap.
HDBaseT - They were exhibiting in the Hilton on the 3rd floor, showing their 5Play connectivity system that can be controlled from a smart phone. Up to 100W of power can be delivered (maximum of 60 volts @ 1.6A) to a connected TV. Their main competitor, DiiVA, was in the lower South Hall showing a similar approach, but with a maximum power rating of 24 watts. Crestron, AMX, and Gefen are now using HDBaseT architecture in their products.
