ST Teaser is 88 seconds long...same amount of time as the Scroll at the start of the films.

The trailer is going to be 88 seconds...that is the same amount of time it takes for the John Williams theme to run with the scrolling text at the start of all Star Wars films.
Interesting J.J. would use that same amount of time.

I guess he could theoretically reveal the new scroll of the film. Show nothing from the movie but the intro title scene.

Talk about giving you goosebumps if all you saw in the movie theater was the Scroll with John Williams music. Biggest tease of all time. It would give you a ton of information about the film without showing you anything.
