It's possible the the end of Shake 4.1 sales may in fact not be the end of Shake. I've felt for a while that the next version of Shake probably would be heavily tied to the release of Snow Leopard with all of it's multi-GPU/CPU efficiencies added, but obviously I don't know. I did read this on a Mac rumor site about a week and a half ago though:

"I'm currently doing research on Final Cut Studio for a technology journalist. I just had a press conference with a marketing big wig from Apple. I quizzed him on Shake and "Phenomenon". He was (not surprisingly) very guarded. But one thing he did confirm is that Apple do not consider Motion to be Shake's replacement. And I got the feeling from him something else is in development. "


There's actually a Shake petition here just in case as well:
