While I do like the base game (It's fun to explore, and I like settlement building), I don't like it for the reasons I love Fallout 1, 2 and New Vegas. The RPG system went completely shit the bed, in exchange for a more linear FPS title. Todd Howard says that the game had some features they were...
So there are some leaks of the DLC around.
Word is its biger than the usual Bethesda dlc in size.
However...
I've seen a 2 minute video of it, its not difficult to find, and some small things are reaviled in it.
It motivated me to make this shit: http://i.imgur.com/Vepj6sH.jpg
