Um... Unless they meant one of the new X or Classic Books that were mentioned that aren't even in Japan currently, they heard wrong. Very, very wrong.
Amazon have been kept out of the loop, simple as that.
Uh oh. I'd just stop if I was you. *laughs and waits for SB*
Oh, I don't believe I'm going to win. I'mma gonna try anyway.

However, onto some good news. Udon was there at the Festival, and I happened to notice that poster. So, being the intrepid Mega Man fan that I am, I asked him about it and he told me that it was for the up incoming English translated Zero Complete Works that many a fan have been waiting for, which he confirmed is coming in February. Of course, skeptical as I am, I mentioned that it had been pushed back before, and he swore that it's in Hong Kong as we speak being published. So, unless he's a liar, hopefully it will indeed be out in Feb. without anymore delays.
Oh, and relying on Amazon is like relying on Wikipedia: some of the things you see might not be true.
