These are the DCU titles that Diamond has announced as shipping this week. Clicking on a link will take you to the DC Comics site for cover art, creative team and story summary.
Batman & the Outsiders #7
Batman vs. Two-Face TP
Birds of Prey #118
Brave & the Bold #13
Countdown to Mystery #8 (of 8)
DC Special: Cyborg #1 (of 6)
DC/ Wildstorm: Dreamwar #2 (of 6)

Justice Society of America #15
Showcase presents: Green Lantern Vol. 3 TP
Superman/ Batman #48
Superman: Escape from Bizarro World HC
Tangent: Superman's Reign #3 (of 12)
The surprise this week is finding JLA #21 out a week early, doubtless so the Final Crisis Prelude can be read a week before Final Crisis #1 comes out.
A big week for me: Batman/Outsiders, BOP, Catwoman, Countdown to Mystery, JSA, Robin, and maybe JLA. Also, Captain America and Mighty Avengers from Marvel, and Star Trek: Assignment Earth from IDW.
