So this news is a couple of days old, but no matter, the next Die Hard in the franchise, aptly named, "A Good Day To Die Hard" has been given an official release date of February 14th, 2013.
Here's the synopsis from 20th Century Fox:
Since the first Die Hard in 1988, John McClane has found himself in the wrong place at the wrong time, with the skills and attitude to always be the last man standing, making him enemy #1 for terrorists the world over. Now, McClane faces his greatest challenge ever, this time on an international stage, when his estranged son Jack is caught up in the daring prison escape of a rogue Russian leader, and father and son McClane must work together to keep each other alive and keep the world safe for democracy.
It'll be good to see Willis back to playing McClane, to be honest though, Die Hard 4.0/Live Free or Die Hard wasn't exactly the best film in the franchise.
