Mangacast catches that beginning March 1st, Infinity Studios LLC is introducing "ebooks" versions (pdf files) of all new titles scheduled to be released:

The purpose of these ebooks is to meet the needs of anxious fans and to allow us to skip the printing process which has so often delayed our release schedule in the past. While we do plan to continue printing a few titles as hard copy books, Infinity Studios will be releasing certain titles only in the ebook format. In addition, Infinity Studios will be releasing some of its earlier unfinished titles (which were on hold) in the new ebook format.
