New Testament Greek Manuscripts Series

One of the comments put me onto a Tyndale House Publishers series, called the New Testament Greek Manuscripts. When I went to Tyndale House website, I found that they no longer own them, but sent me to a mission website where they can be purchased. They are book-by-book complete manuscript traditions of all verses, I think. But, there are not volumes for every book of the NT. Since Tyndale no longer owns the series, I wonder if this means that there will be no more volumes. Does anyone know?
