I swear that trailer for the SE was on the 2004 bonus disc. I love it too:p
Also, if your going to include the making of's from the vhs there is a far better version of those included in the big limited edition SE set, the one with poster prints and a medalion of some sort. Included is a documentary called "the making of the star wars trilogy special edition" or something, and it consists of all 3 making of's from the vhs's edited together with more footage to create a documentary. Something else that would be interesting to have would be highest quality possible versions of the "Anatomy of a Dewback" web docs from starwars.com.
