May I offer you a translation by native Japanese. This article is dated 27 Dec.
The first para says “Nikon announced on their product information website that the stock holding of D40X finished. There was no mentioning of D40.” (The second para explains the difference between D40 and D40X, so I skip.) The third para is post script on 28 Dec, saying that the above announcement was not on the website anymore. The termination of stock holding of D40X is only for domestic market. Also it was confirmed that sales of D40 continues.
(End of translation.)

I think the postscript is not so logical when translated. But that is what it says. There is another website by Nikon indicating in red character that they now stopped taking order for D40X. See
