I see Sony has a new Direct View HDTV. The KV-40XBR800. I think this is the largest Direct View made.. if not, Are there more? I want bigger but want to stay with Direct View to avoide all the Calibration issues and hassles associated with RPTV. I'm not all that knowledgeable about features. What are the essential things to look for? i.e. 3D Comb Filter, etc. Most people feel Sony's are great TVs albiet overpriced... Thanks for any comments and advice.
