I would love to fight sand worms, "sammoths", wolves, tigers and other critters but unfortunately I think that most animals are not going to be in the game. Chris has said adding fightable animals would break the combat system and it would require too many new animations.
But that really looks cool

I still hope that either Chris would decide to add animals, or someone made a huge mod so I could live like a hunter, hunting strange animals and running away from giant monsters.
