I recently reviewed the following 3D modeling and animation packages: Wings 3D 1.2, Silo 2.2, Modo 401, Cheetah3D 5.5, Cinema 4D R12, Blender 2.54, Maya 2011 and wrote about my impression of each in my blog. 3D Modeling and Animation on OS X | Thomas Grové's Blog
Also, there are new versions of Blender and Cheetah out this month. Automatic FBX export still seems to be broken in the beta Blender (now at 2.55).
