Updated September 14, 2015 at 5:45 p.m. EDT: According to a DC spokesperson, Doomed and Green Lantern: The Lost Army were originally intended as "6-issue limited runs" like the Harley Quinn/Power Girl, Bizarro and All Star Section Eight series.
Neither Doomed or Green Lantern: The Lost Army were previously solicited as being miniseries like those three mentioned by DC.
Updated September 14, 2015 at 5:00 p.m. EDT: Writer Cullen Bunn has confirmed to Newsarama that Green Lantern: The Lost Army has also been cancelled, with November's #6 being it's final issue.
"Issue 6 will be the last issue of the series," Bunn tells Newsarama. "There's more to the story of these lost Lanterns, and their story will be resolved in another limited series or in the pages of another Lantern book. I developed a plan for them, and I hope to be part of how it plays out."
Original Story: Add two more DC titles to the five that was announced as ending Monday morning -- with another one missing in action. In the DC December 2015 solicitations, both Batman '66 and Sensation Comics Featuring Wonder Woman are listed as ending with that month's issues.
In addition, Green Lantern: The Lost Army is absent from the December solicitations. The November solicitation for Green Lantern: The Lost Army #6 featured no "Final Issue" tag as the others did, and it wasn't among the listed titles reportedly cancelled on Monday morning.
DC has not yet responded to inquiries about the status of Green Lantern: The Lost Army.
