Re: Xbox Elite has HDMI!
I believe it will output 1080p but it is not HDMI 1.3 like the Playstation 3.
That means that any movies played on the optional HD DVD add-on will be limited to standard Dolby Digital soundtracks, not the higher resolution Dolby Digital Plus, Dolby True HD, or DTS-HD Master Audio.
I also believe the standard 360 version will also have HDMI so the only diffrence between the 360 & elite will be the hard drive size & color.
You also want to get as new of a build as possible since they will have been modified already with bigger heat sinks to (hopefully) ward off the red ring of death.
