so amazon has a solit for The Complete Clone Saga Epic - Book 4 up (coming out in December)
and it lists New Warriors #61 as one of the collected issues.
Now New Warriors is a prologue to the Maximum Clonage story, but I don't think it's super important. So we may still get the rest of Scarlet Spider's appearances in New Warriors (He joins the team in #62 and appears in every issue until #71, even after he becomes the New Spider-Man)
Without bothering to look up a reading list, that sounds like it very well could span 8 volumes like you suggested. I guess it would depend on how they collect the issues between when Ben becomes Spider-Man and Revelations.
