I've heard that they will be remaking Tomorrowland to make it more Star Wars oriented. Of course, that's just a rumor, nothing official. BUT I will say that the Blue Sky Cellar has been closed for a while now, and that's where they showcase plans for upcoming developments. (They had exhibits on Cars Land and Fantasy Faire before they opened.) I'm guessing they are redoing it for the next big thing - a Star Wars version of Tomorrowland is my guess.
Personally, I like the way it is now. I know that by now, it's outdated, but that's kind of part of the magic of Disneyland. There's a lot of history there! I know time marches on, so I'm just hoping they don't change things around TOO much. Star Wars is a big enough franchise as it is, it doesn't need it's own land.
