I think it will be down to this: Anyone who isn't asked back or who doesn't want to come back will be portrayed as dead (or, rather, their characters will be).
Also, some of those who DO come back will end up being killed off if either they, or Singer, want only a one-off appearance.
It seems a wrong way to do a film (basing it on availability and preferences) as TLS did the same thing, but if they are wanting familiar faces it will probably come down to that.
