I'm teaching an intro class for 5th-7th graders that already have some experience with Scratch (visual block based programming). I think Processing, especially in its static mode, does a good job at helping make the leap to actual programming (typing in code) without exposing the novice to as many real programming language constructs like Python does. Since it so trivial to get drawing, animation, and interaction going with Processing, I also find it is more fun for the first timer, especially the ones who don't have a natural geek bent. I'd say go with Python for year two, when you know you have the ones that cared enough to return for more.
