I myself have no idea, but maybe this will help ya.

HDMI is something the other system has and the executives at Microsoft :D "hey this looks like a good idea" and now its on the the 360 :D To answer your question it is a superior way to broadcats a digital signal fo hdtvsV2FLUXER

... It is not superior. It is simply another type of cable to transfer a signal to a television albeit in digital form. Component cables can transfer 1080p just like HDMI.

HDMI transmits video and audio signals in a pure digital form.

The biggest "benifit" will be to HD-DVD users.  eventually HD-DVD and Blu-Ray movies will have a copy protection known as HDCP.  Currently the only way decode and use disks using HDCP is by connecting the player to a TV via HDMI.   Currently none of the movie studios are implementing HDCP, that I know of.

Am I to assume that The HDMI cable is specific to the HDMI port and will not be compatible with the current Xbox systems? and also if my tv is only 720p would HDMI even be neccessary because i read somewhere that HDMI is only for outputting 1080p for movie playback.... bluntmastaslaya
