Atlus bumped the early bird bonus for Catherine up from a soundtrack CD to an art book and soundtrack disc.
First print copies of Catherine includes a sound disc with eleven tracks arranged by composer Shoji Meguro, a booklet with commentary about the songs from Meguro plus a making of the jacket illustration bit from character designer Shigenori Soejima. That picture of Catherine on the right is noted as a temporary design on the Atlus blog.
Maehara from the PR team also mentioned some of the feedback she heard about Catherine’s cover art. Most of responses are unsurprisingly "ero" or erotic.
