According to various listings on eBay, like
this one from grapemusicland, in addition to the 100-page photobook, the album is described as having hardcover packaging and a bonus poster. The bonus poster is one of the previously released teaser promos featuring one of the members and will be randomly chosen.
Looking at the YesAsia listing, the weight of the album is given as 700g. That's pretty heavy for an album. At 700g,
Pinocchio is almost the same weight as Meisa Kuroki's
MAGAZINE album.
I'm still going to wait for a repackage but it's nice to know that SM is putting a lot into this release. I doubt they'll do it twice so if there is a repackage it'll likely come in much simpler packaging.
