But really, is there a high amount of TV's that support 1080p over component?
I believe the new Samsung S series DLP sets released earlier this year will accept 1080p over component and a few lesser known brands like HP do as well. The new DLP sets from Toshiba and Mitsubishi will not and neither will the SXRD sets from Sony. It is worth mentioning that most of the new 1080p sets have a PC input with either a VGA or DVI connection that from what I've read from owners on AVS can handle 1080p.
Most of the 1080p content available now is HD DVD and Blu-ray which is limted to HDMI so I understand why most sets don't bother to support 1080p over component. It will be interesting to see if the new sets released in Summer-Fall 2007 add support since by then I'd expect the 360/PS3 Core base to be 12-15+ million. We should get hint of whats to come at CES in January.
