Lots of people think its going to be the merging of Kidzville and Planet Snoopy to form one of the largest kids areas, but I have a hard time believing they would be doing all this hype for a kids areas...
Not sure if the rocket is an indication of the ride, or just an allusion to the "countdown" mentioned, or both, but that might indicate a record-breaking drop tower. Or, at least, that's the first thing I thought of when I saw the image.
If you look at the image above the part where the tip of the rocket starts to widen, some people say that the darker part of the moon looks like Charlie Brown with a baseball cap.
