Mostly new stuff in the Studios I think. Was Toy Story Playland there last time you were there? I can't remember when that opened, but includes RC Racer, Parachutes Ride and Slinky Dog Ride. Ratatoullie is definitely new, it opened last year.
There is an official Meet Mickey point in the main park and also a Princess Pavillion to meet the princess'. I can't think of anything else new in the main park.
