Just think of the vast information that you can think of that you would like to see in a upcomming DLC. IA. A new world that has cars or bike's you can build if you
pick a certain attribute. Or maybe you want to see the Brother Hood come back and seek victory. What ever you can come up with will make the experience for you and others that read your post. Heck it might even give Bethesda a idea of what everyone is looking forward into what you you like to see.

Joshua Graham, the Burned Man, and the Malpais Legate.

Got two threads for this actually: http://www.gamesas.com/index.php?/topic/1174359-what-do-you-hope-to-see-in-the-upcoming-dlcs/
