This has been common knowledge for some time now.
TBH how are they going to use the PS3 as a showcase for Blu-ray if they supply it with the lowest quality cable available (bar RF).
The majority of consumers will not know the difference in cable performance and think that they are getting the best available picture. I cant stand my 360 on composite and have to have it on component and this is at 480(i/p) I'd hate to see it in compoite on a TV that could do 720p or 1080p.
