Remember that amazing price reduction that Apple announced along with the release of Shake 4.1 (well, only for the Mac version)? Seems that all that glitters isn't gold.
Apple sent a message to their Shake users (via a listserv) and let them know that Apple will no longer be actively developing Shake, but they are working on a brand new composition product (maybe). They are offering to license the code to production shops (or users I imagine) for $50,000 (or they can get a refund for the remainder of their service contract). That might seem a little costly but you also get 5,000 licenses which is a great deal.
