masada songbook

I've been wondering about the number of compositions in the Masada songbook. In the press text to "Masada Guitars" it says: "In 1993 John Zorn began composing and performing his 208 tunes that now comprise what is known as the Masada songbook." But counting the published tunes (drawing from the DIW recordings as well as the several live and chamber ensemble cds) they only add up to about 115. What about the rest?? Is Zorn still having them up his sleeves for future releases? Also I'm curious if there are any plans to publish them as sheet music, sort of "The Masada Fake Book"? Any info on that would be much appreciated.
