UPDATE – It was previously reported that World’s Finest was amongst the list of cancelled titles this August, however, that has proven to be incorrect.  It was an error in the DC solicitations for that month and has been confirmed by DC Comics that only six titles are being cancelled.  The updated article is below.
This August looks to be a grim one for DC fans.  DC Comics will be giving the axe to seven of their current titles that month, including Superboy, The Phantom Stranger (currently known as Trinity of Sin: The Phantom Stranger), Birds of Prey, All-Star Western, Trinity of Sin: Pandora, and Batwing.
Four of these titles joined the ranks of the New 52 during the first wave, back in 2011, and have lasted over 30 issues each. Â As of August, DC will have cancelled 46 titles over a 3 year span, 31 of those from the original first wave of issues. Â And with each issue booted out, new blood joins the ranks. Â We’ll have more on what new titles will be added as they are announced.
On a side note, amidst all of the cancellations, one title will be doubling its release, becoming a twice-monthly series.  That title is the new Suicide Squad spinoff, Harley Quinn, with issues #9 and #10 both releasing in August.
Here are the details on each comic’s final issue:
