They won't get rid of the backlit keyboard.. the whole point is to make products better, not worse. Based on the rumors and whatnot swirling around this new 12" retina mba I've been a huge supporter of what I'm hearing and planning on buying one as soon as I can, but the loss of backlit keyboard would be a big red flag. I just can't envision Apple going back on that for the sake of thinness, especially since the backlighting mechanism for the keyboard appears to be a nonissue when dealing with thickness (meaning the keys depress in deeper than the backlighting mechanism, so removing the backlighting wouldn't help reduce thinness at all).
