Another theory corresponds to the first, where numbers stand for clues so as to keep the fans deciphering on track. Since there are so many letters to fill in, it's possible that we are left with a few at the end. It could be that the letters ''left over'' would be the anagram.
===The Stand or other books===
Due to the new clues, 24.19.X, it is unlikely the numbers are referring to the 19th track of YearZero, since there isn't one.
Also the Bible references don't make any sense, they don't mean anything in contribution to the story, and also the ARG makes wouldn't make it that dull and obvious.
References to books like The Stand, and Slaughter House 5, have led some to believe that possibly these books are the clues given by the numbers. The Stand (reissuing of the expanded version) is the 24th books Stephen King has written.
