Well just got back from the preview day of C4 for fan club members and I'm almost too tired to write a report (if i do it'll be in the entertainment section) but thought I'd say that there will probably be no announcement regarding Star Tours this weekend.
George Lucas is currently in Europe RIGHT THIS MINUTE working on Indiana Jones 4 with Spielberg. So he won't even make an appearance to the 30th anniversary celebration.
But if any thing DOES get revealed, it will be tomorrow night during the grand opening ceremony. I will post as soon as I hear anything.*
*meaning I will post as soon as I get home safely from too much star wars.
