For those of you who may be Hyperspace members after ya watch the trailer look through your internet cache and the trailer will be in there. Ya wont be able to save the trailer by normal Quicktime means (with the 'Save as Movie' option in Quicktime) but you will be able to save it by looking through your cache and moving it to a different folder and saving it there on your comp. I used todo this all the time before I knew how to umm lets say "do some things that should not be mentioned on a forum".
I will be at work when the trailer comes out so I wont be home until 5pm PST but after viewing the trailer look through your cache and you will find the trailer in there, yes even streaming video saves the file in your cache.
Be aware though Lucas and SW.com will have people patrolling the internet today putting out fires (so to speak) of forums and websites that use the above method and similar means to host the Trailer on their own sites. So even if ya do get it and put it on the net to let others see it just be warned that ya might get contacted to take it down asap as the places that get it today are suppose to have it exclusively this weekend for their members before it comes out in general release on Monday.
