I have "Empire of Dreams" on the screen in front of me still framed on the original crawl. "Star Wars" dissappears just as the line "Rebel spaceships, striking" scrolls onto the screen. This is the second line of text, and the the "Star Wars" logo fades completely out just as this line is about 3/4 visible at the bottom of the screen.

It appears from your screenshot that the trailer may simply be less cropped than the "Empire of Dreams" version, which would actually be a good thing. This would explain why the "Rebel spaceships, striking" line is fully visible while the "Star Wars" logo has not yet faded out.

I have not yet seen the trailer, so I'm going strictly on the screenshot here, versus my "Empire of Dreams" DVD.
