Eye of Terra: Already confirmed to be an anthology. Based on the cover-art, it is likely a Great Crusade collection. http://1.bp.blogspot.com/-V7e5-jz1xa...00/unnamed.jpg
The Path of Heaven: Book 35, Scars sequel. White Scars return to Terra, start of the final third of the Heresy.
The Silent War: Already confirmed to be an anthology. Based on the cover art it is about Garro and Malcador, likely it will contain all the Knights-Errant stories so far in print form.
