Brian Michael Bendis has shared information that the Question will be appearing in his Action Comics run. Answering a fan question on Twitter, Bendis related a conversation with Ryan Sook who commended Bendis for including the Question in the upcoming Action Comics #1005 script.
@BRIANMBENDIS is there any way you could do a Question miniseries?— Darnell Banks (@DrnllBnks) June 8, 2018
Well to quote Ryan Sook who just emailed me after reading Action comics 1005: “THE QUESTION!!! Awesome!” So question fans, buy action comics :-) https://t.co/gvXyEfB6iU— BRIAN MICHAEL BENDIS (@BRIANMBENDIS) June 8, 2018
Bendis isn't clear which version of the Question they are referring to. In current DCU continuity, Vic Sage (not as the Question) last appeared in 2016's New Suicide Squad "Freedom Arc"; Renee Montoya (not as the Question) has appeared in the current Batgirl & Birds of Prey series.
Action Comics #1002 is scheduled for September, and with a monthly schedule Action Comics #1005 would be projected for a December 2018 release.
