April 17 marks a somber day for Grand Theft Auto fans, as the highly anticipated GTA 6 reaches an unfortunate milestone.

As with their earlier Xbox 360 debut, "The Lost and Damned" and "The Ballad of Gay Tony" will be available to existing Grand Theft Auto IV owners as premium-priced downloadable content.

Grand Theft Auto 5 first launched on PlayStation 3 and Xbox 360 in 2013, but continues to show impressive staying power even in the face of the impending Grand Theft Auto 6 launch later this year.
