I saw it at
D23. It looked like GREAT fun to me.
I saw kids playing it, they entered the DL park and met various characters. Each character has a different personality, and interacts differently. I saw Cinderella, she hugged the child, and danced with her.
I was wishing it was not just on X-box. We have trouble with X boxes here, and currently my son's has the red ring of death and is out of warranty.

The reps at D23 said it will NOT be offered on another platform like Wii.
I want it though.
