I don't see Joss seriously venturing back into any live action treatment of the Buffyverse or its various characters any time in the next five to ten years, simply because he wants to prove to the world, and himself, that Slayers and vampires aren't the only thing that he can sell a marketable story or series about. By the time, if at all, he finally does decide to return to the world of vampires and demons, it will almost certainly be with an entire cast of new faces. For that reason, I seriously doubt that we will ever see a Spike movie, a Ripper movie, or a Buffy movie involving either him or any of the original crew or cast. It's fun to dream and to speculate, but I don't think that it'll ever go beyond that stage. So enjoy the new Joss-less Buffy movie, folks, or ignore it completely. The cruel fact is, it's all that we're likely to get for a long time to come.
