Villain for Wolverine spin-off movie?

Who do you all think should be the main villian for the Wolverine spin-off movie? I'd pick Sabertooth if he wasn't already introduced in X-Men 1 (which did a poor job of introducing the Wolverine/Sabertooth relationship). So I think I'd like to see Omega Red as the main villain
