I don't think the info is right about Bravia TV's being the only TV's to support PS3 3D playback. A lot of times the info at consumer shows are not accurate.
This guy is the only guy I'm hearing this from and I have read a lot of articles about Sony/PS3 3D at CES 2010.
No other article on the OP said anything about PS3/3D being exclusive to Bravia TV's, this guy must have been misinformed.
