Forgive the thread-spam... I'm researching/producing an animation in trad 2d using 3d as a rotoscope base, and a friend found this for me - it's got a robotech look to it, and it's epic!

I'm pretty sure The Simpsons has been using Flash to animate their show like most western animation studios for some time now. Unless they've outsourced to what appears to be a version of the forced labor dungeon from Temple of Doom and bought them an Adobe license I think it's just a joke.
