It's always good to have clarification, and it's important to note that Sony didn't seem to have any choice in the matter.
We've all heard about the new "K chassis" PlayStation 3 models, which apparently affected high-definition content. It seemed that an HDMI cable would be required for viewing high-def movies and games; component cables would no longer cut the mustard. But Sony has since clarified the issue :
"The new CECH-3000 series PS3 requires HDMI only for BD movie output in HD, in compliance with AACS standards. PS3 continues to support component output for HD gaming and streaming content."
They're referring to the Advanced Access Content System that is a standard for DRM, and states that HD video resolutions are limited to HDMI and DVI cables. As of 2014, Blu-Ray players won't have any component ports at all; it appears the initial report based on a GameStop document was inaccurate. Even so, this news could affect those with older HDTVs or those who don't have enough HDMI ports for all their devices.
