Though its kind of useless to discuss tools here.. I mean they get updated every 6 months and its hard to keep up. Still Autodesk Maya 2012 (sounds like doomsday package:) has some 'interesting' tools for Animators. I liked the Craft Director Tools which now come embedded, so animating vehicles is cake nw and Motion trail editing which was much needed. Also some more motion builder additions and some great GUI setup system for rigs.
