The official Comic-Con website has confirmed that during Warner Bros’ panel on April 1st, DC will be making an appearance.
The description for the panel states that “sneak peeks” at films from WB, New Line, and DC will be shown, which could indicate a new trailer dropping for Justice League.
The latter will be out before San Diego Comic-Con 2017, leaving only Justice League ready to deliver on footage for those in attendance.
However, with fans wanting more, it could be WonderCon that brings about new footage – or even announcements.
