"Die Hard 5" Begins Filming In 2011

Just found out that over the weekend, Bruce Willis confimed (in an interview with MTV) that the script for "Die Hard 5" is completed. He said that right now, the writers (with Willis) are just fixing a few things before filming begins sometime next year.
He never gave much away about the plot. No one knows if the film will still be called "Die Hard: 24/7", he just called it "Die Hard 5".
It's unclear wether Lens Wiseman will return, as "Underworld 4" goes into production in January 2011. But it has been rumored that Kevin Smith is possibly in the running for director for the fifth film. Willis would like if Wiseman did return, as well as Justin Long too.
