Definitely like this change:
My hope for 4e:
1) Normal Vision: Concealment in areas that aren't well lit.
2) Low-Light: No concealment unless in total darkness.
3) Darkvision: Vision in complete darkness.
No more counting squares of illumination. I just tell my players what the lighting the area is and go from there. Make darkvision and rare and powerful ability.
