The Bethesda Blog points the way to this new text diary written by Josh (J.E.) Sawyer where the Obsidian Entertainment project director talks a bit about the NavMesh in Fallout: New Vegas, as well as the overall experience of working on their imminent RPG sequel. The blog also embeds the Fallout New Vegas Developer Diary #6 focusing on the voice actors in the game, starting naturally with the return of narrator Ron Perlman, also hearing from Matthew Perry, Wayne "Mr. New Vegas" Newton, William Sadler, and Kris Kristofferson. With the game due tomorrow, the Bethesda Blog also offers details on New Vegas midnight launches and digital unlocks. Finally, they also announce the first DLC for the game, though at this point it is only expected for Xbox 360.
