Yup, we just bought it, $39.95 USD @ Kay-Bee Toys.
It looks to be even better than the original; they claim 100 hours of playtime on the back, plus more abilities and more open-ended gaming. Supposedly the story arc changes depending on how you arrange the georama items, etc.
I haven't played DC1 myself, but my wife is a bout 95% done and eager to move on to DC2.
Hope this helps!
