Bump because I just read that, and apparently it IS happening, and I also just finished Fallout: New Vegas so I really want to rant about how great Fallout: New Vegas is. I poured over 80 hours in to the game, and played through every DLC, and one of the things that has stuck with me the most is the companions. I loved how NV's companions developed their personalities as you helped them with their problems, how they would start to treat you differently, act a little more personable around you. Let their hair down, you know? NV actually felt like you were making a friend, it actually made you care about your companions, and what might happen to them depending on the decisions you would make. I wish Skyrim was more like NV, in this regard. Looking back, and after spending about the same amount of time playing Skyrim, I remember the companion characters being so ... 1 dimensional.
Also, hardcore mode in NV was the coolest thing ever. Actually having to eat, drink, and sleep in order to not die made the game so damn immersive.
So yeah, I'm really excited about this. I really hope Obsidian brings a lot of great ideas to Wasteland 2.
