Bruce Willis Hints "Die Hard VI"

Just found out today that in the interview with a magazine, Bruce Willis hinted the possibilities of a sixth and final "Die Hard". This is what he said, "I want to do Die Hard 5 then one final Die Hard movie (Die Hard 6) Then I'll finally hang that white vest up for good." He then joked by saying, "At the moment, I can run and I can fight on screen. But there will come a time when I no longer want to do that."
