Thats fantastic news!! I always love Tim Burton's takes on familiar books, he always tries to stay as true to the original as possible (Charlie and the Chocolate factory, for example.)
A little dissapointed that Wonderland will be CGI. I was hoping he'd take the claymation/stop-motion road again. I always loved the transition from live-action to stop-motion he did with James and the Giant Peach. I'm also very leery of Disney's ability to do a really good CGI movie.
Don't screw it up, Disney!
