No, what he said is that the 2 books of the so called "2nd Edition" are just a full and not revised copy, a simple reprint of the one and only 1st Edition, the one from 1993, just for technical reasons it is split into two volumes, the content should be just the same.
As it is just a reprint in copy-shop quality, it will not be right the same as the original, but the original itself is just black and white with some greyscale pictures, so I think it will be not too bad at all.
If he makes an ebook...well just get aware where you are, he would only sell it once ;-)
Then he apparently is working on a new Edition, a real 2nd one, but who knows if and when he will have finished it....
