A while back there was a press release about Bethesda's and Obsidian's DLC info in that they detailed Honest Hearts, Old World Blues and the Lonesome Road as well as mentioning several other planned DLCs. And in the mentioned DLC's they said that one will take place in a "place players thought they'd never see" I have pondered this and I have several Ideas though its only speculation. One is that the player is able to go to Hub (shady sands and such) back west in California. Another is being able to go to Flag staff the capital of Ceasar's territory. or even area around the Lost hills headquarters of the Brotherhood of steel. The possibilites are endless my friends. but if anyone hears of any info regarding the "place players thought they'd never see" lets us know otherwise post where youd like to go in the DLC.
