I didn't know the Model X was at CES. I guess it makes sense though. What other car would fit in on the electronics super show floor. ;)
I thought PhoneDog had a nice review of what he saw there: http://stories.madcards.com/3145/25400/TeslaModelXImpressions
I like the "Falcon" doors they show off. Not sure about the name, but the clearance seems decent.
That was a model X prototype. While the production version will look very much like that one it will also be different. How? Nobody knows yet as it has yet to be shown to the public.
