I'll be getting Fallout 4, I don't have a Wii U. I liked Fallout 3, but it had quite a few significant flaws, New Vegas was a lot better and I'm hoping Fallout 4 will be in the vein as that. I'm also hoping you can disable or leave companions completely behind as I hate having them along in FPS games.
I think Fallout 4 will be either mind-blowing or a slight disappointment, there is only a very tiny chance that it won't be good. Hoping for mind-blowing! Loving the customization bits and base building so far.
