While we knew Tatooine would be featured in the updated Disney Star Tours ride, MiceChat.com displays some picture evidence that Coruscant will be included as well. Visit here for the source article but you'll have to scroll a little over halfway down the page.
Thanks to Patrick for the link!
UPDATE:Starwars.com reports the following in regards to Star Tours and Coruscant...
"The adventures continue for the Jedi in all of us! Bridging that "long time ago" between the two Star Wars trilogies, the spectacular new Star Tours adventures in 3-D will debut in 2011 in Disneyland park in California, and Disney's Hollywood Studio theme park in Florida.
The attraction will take voyagers -- for the first time ever -- to Coruscant, as well as other destinations in the Star Wars galaxy. The power of the Force and the magic of Disney once again combine for this immersive experience in Tomorrowland!
Here is an all new image released from the new Star Tours adventure: the Starspeeder zipping along in the skies of Coruscant."
