Bethesda has announced by way of its official blog that Fallout: New Vegas Ultimate Edition will compile every piece of DLC for Obsidian's return to the Fallout franchise in one little package. The Ultimate Edition packs in Dead Money, Honest Hearts, Old World Blues, Lonesome Road, Courier's Stash, and Gun Runners' Arsenal.
The version of the game I should have waited for instead of springing for the plain Fallout: New Vegas edition will be out February 7th, 2012 in North America and February 10th in Europe for Xbox 360, PS3, and PC.
