I am also interested in a 40" model scaled for a smaller-sized room, and came close to purchasing an XBR9 a few weeks ago. My initial impressions of the new Sony lineup are favorable enough to encourage me to wait until some reviews are provided for the new NX 700 and NX800, which are due out in late February. I am leaning toward the NX700, but am disappointed that it is not 240hz. Apparently, the only way one can get a 40" with 240hz is to get the 3D ready HX800 model which won't be out until summer, and, of course, at additional cost.
Also, although I really like the monolithic design, especially with that new metallic base, I am a little concerned about how much reflection will be generated by that new glassy screen. We'll have to wait to hear what the first-hand impressions are, and, hopefully, they will start coming in soon.
Perhaps some opinions and impressions of those who attended the CES and saw these models will become available here.
