I think my count is up to four books that will be cancelled by DC Comics as of August.
Legion of Superheroes and Threshold.
And now two new ones with Demon Knights and Dial H.
I wasn't a fan of either of the New 52 relaunches of LOSH or Demon Knights, never read Dial H, and Threshold didn't seem to catch on as it lasted only 8 issues.
Maybe four new Batman titles to replace them?
