At Star Trek News there is an "odds" page as to probable outcomes for the various characters.
Future movie deals do indeed seem to loom large in their thinking.
For example, they mention the possibility of killing Janeway just before the end (this has ANCIENT precedents...), but then they discount that idea because they think she has more "star power" than Robert Beltran.
Go figure. But in any event, after having spent almost 7 years waiting for them to finish their mission, they BETTER get home.
