I just got my new XBR4 52" from BB yesterday. Thanks to all posts on AV forum, it was very helpful. It was a hard choice between it and the Sammy TN 81. Both were excellent sets, but it came down to the anti-glare coating on the Sony. I'm very happy with the XBR4. It really does look 3D, must be the DRC feature or something. As for clouding, I don't see any when looking directly at the TV in a dark room with a blank channel. However, I do see some unevenness when I move to the extreme sides/angles. So no big deal to me. No dead pixels. The built-in speaker sound is much better than I thought. The Xrossbar menu system is cool, like PS3. Overall, no regrets.
