Well as you can see the industry will be going towards HDMI. The major (and possibly ONLY) reason its going in this direction is for copy-protection. Before entering my foray in home theaters I did some reading and basically found that HDMI/DVI aren't drastically superior to component. Blue Jeans has an excellent article here.
Some good info in that article such as once digital data is lost, its gone forever.

HDMI is also preferred vs DVI since it sends both the video and audio signal over wire whereas DVI is only the video feed. The industry can now place copy restriction on HDMI connections to prevent perfect HiDef digital copies. For now I am content with component but will eventually use HDMI since its less cable clutter in the back of my setup.
