The publisher's senior vice president of sales Bob Wayne said that the fate of the franchise will be decided after the prequel's run has concluded.
"We are looking forward to the conclusion of all these series and seeing how they all weave together and see what everybody's opinion is of the whole thing when they see it all together as a whole organic story," he told ICv2.
DC recently announced that a two-issue Moloch comic has been added to the Before Watchmen series, but has "no plans" to expand it further.
Before Watchmen is now into its fourth month, having debuted with the release of Darwyn Cooke's Minutemen #1 in June.
The series continues next Wednesday (September 12) with Comedian #3.
