DC has pulled the plug on the Vigilante: Southland miniseries after the release of #3 in December, cancelling the three subsequent issues left in the miniseries solicited for January, February, and March 2017. This would be one of the first casualties of the "Rebirth" era.
The unreleased issues will not be re-solicited in individual form, but according to DC it will be included in a planned collected edition of the limited series. Issues #1-3 will be made returnable by the publisher in an unannounced timeframe.
Vigilante: Southland #4 was due out on shelves January 25, with #5 scheduled for release in February, and #6 originally solicted for March. An Amazon listing for the collected edition lists the release date as May 2.
