I'm of course looking at this from a demoscene centric point of view, but why would I as a user want to trade a known working platform (060-accelerator) for something that's not compatible enough (the vampire), if that results in a lot of demos not working anymore. Especially as the Vampire most definitely won't be getting any decent demos of it's own.
(EDIT) I do agree with others though, that there's a better possibility that people will get a Vampire to complement their collection. But the Vampire won't make 060-accelerators redundant in the scale you seem to suggest.
