Sony makes a 60" projection LCD. On an in-store closed circuit demo, picture quality was, to my eyes, better than cheaper plasma's and as good as the better, newest plasma sets. Street price for the 60" seems to be around $5k, which is about what the 42" plasma's seem to be going for. Since even the street price on the 60" plasma is north of $15k, the lcd is a comparative bargain. I also would be interested in some technical analysis and comparisons of the two technologies.
