At the Osaka World Hobby Fair, Capcom formally announced a new Complete Works art book, one that would compile various artwork from the entire Shooting Star series. If the past is any indication, Complete Work/Perfect Works books usual come out in honor of a series' end such as Zero Official Complete Works and RM.EXE "Himitsu Complete Illustration Guide." (What of R20? Meh, maybe that's an exception)
The book is set to release in late March, 2009. Thanks John for the tip.
