The models will never be exactly the same. Also one could argue that deathclaws are not looking all the same (like centaurs).
It's already known that companions in New Vegas will have their own story and - if they travel with the player - give some special stuff. Raul, as example, gives a temporary perk which makes weapons and items break less fast, etc.
verevoof said:On companions, I like companions, but they need to have sort of use to them instead of just combat. Companions in Fallout 3 was unnecessary because they really brought nothing to the table that you the player couldn't do. I'm hoping that Obsidian improved not only the companion combat, but gave them use, skills that you as a player don't have. Then, of course, that would mean that players can't be a master of all trades. Or shouldn't be, anyway.
