Like Stan, I think the main problem here is that you chose to repeat (most of) NR's words in the title of your post.
The use of the phrase "fix for green tint" suggests that Nikon have admitted a fault and have developed a fix. But... nothing in Mr Bershatsky’s blog post - whether it is true or not - supports that conclusion. All he says is that Nikon adjusted the LCD calibration of his camera to be more to his own taste.
I believe Nikon have said that the newer camera LCD's do look different (in colour temperature) in some lighting conditions, but that this is actually more accurate than previous models. I don't believe Nikon consider it to be a design fault, nor do I think they are looking to "fix" it.
