In a couple of early articles in SoCal papers about the DCA makeover, there was some talk about a possible name change down the road. As far as I know, Disney is not officially saying that they are changing the name (or we would all know about it). In fact, they may even be saying that they are NOT changing the name. My personal feeling/hunch is that somewhere down the road they WILL change the name in some way. I think that maybe once the transformaton gets underway and they see how the park eases into the transition with all the new additions and everything, they will tweak the name a bit to make it fit better and make it more appealing to a broader audience. It may be something as simple and subtle as Walt Disney's California Adventure. It could become something as cheesy as Hollywood Adventure! There are pretty significant things happening in DCA over the next few years. I think it has been said that even the park mascot (in printed material and photos) will change from Grizzly Peak to something new. So given what happened with EuroDisney and Disney-MGM Studios, I don't think it is out of the realm of possibility that a few years from now we may see a name change on some level. I think they just don't have official 'plans' to change the name at this moment.
