[Harry Potter] why didn't Voldemort create a new horcrux?

 when he heard that harry was hunting his horcrux, why didn't he make a new one?

Maybe there wasn't enough soul left?

The fact that his soul was so unstable that he made a horcrux out of Harry without even trying to, might mean the recipe doesn't work for him anymore.

Or he was too arrogant to think they'd be able to find all of them. 

I think he was more focused on complete domination than ending up as a shadow in the forests of Albania again anyway.
