Masamune Shirow, the creator of Ghost in the Shell, will release the fourth in his series of Intron Depot art book collections in Japan this June.  Intron Depot #4: Bullets will retail in Japan for around $28 (2950 yen).  Retailers here in the states, even those who don't normally carry much in the way of manga, have done extremely well with the previous volumes in this series, which are published in the U.S. by Dark Horse.  2004 should see renewed interest in Shirow here in the States thanks to the release of the new Ghost in the Shell: Innocence movie and the debut of the Ghost in the Shell: Stand Alone Complex TV anime on the Cartoon Network this summer.
