As of right now, aside from TRONorail, there is very little promotion for TRON:Legacy at WDW. California has the elecTRONica dance party, but there has never been any discussion of that type of event in WDW. The only guess I have comes from a business perspective. Movie companies allocate specific dollar amounts for advertising expenses when movies are released. Disney spent a TON of marketing dollars on Toy Story 3 this year, mainly because they knew they would be able to profit off of all of the merchandise generated from the movie. Hence forth, Toy Story probably had a bigger advertising budget than TRON:Legacy, because the original TRON movie was more of a limited cult following. But I am all for a TRON attraction in Tomorrowland or EPCOT... so we'll just have to wait and see what the future brings!
