I don't think so, necessarily. And my point isn't: they should do this, or they should do that. I'm looking forward to whatever it is, and they've already decided regardless.
But... all the pieces are there for the Surtur saga to be the basic story here. A looming threat that is too great even for Odin to deal with. The casket of ancient winters, Malekith, Algrim/Kurse.
It's still definitely possible that this movie will just be the first half of the story, though. And that could be the better choice. The thing is... Surtur is a "last act" sort of character anyway. He's never going to be around for the whole film.
