Apple announced an update to Shake 4.1. They also dropped the price from $2999 to $499. That's a significant price drop (and don't forget Shake had been $5K prior to that!)
I guess I'd be excited if it wasn't for the fact that I haven't even broken the seal on Motion. I don't really need Shake as it's more for 2D/3D compositing (so I guess I have to learn Maya before I can really have a use for Shake!
