I mean let’s be real here does anybody really want a Zatanna movie or a John Cena peacemaker series? You could easily allocate those assets to a Snyder projectI think could both perspectives be correct at the present time. Warner Bros are very determined at this point to let that be the end of the snyderverse. They have multiple DC projects in production and any further inconsistency in direction will further reduce the dwindling interest of the general public.
With all that being said if the Snyder cut exceeds all expectations by a GREAT deal I can see AT&T possibly continuing the universe in film or series form. AT&T have already shown their power with the creation of the Snyder cut, the release of major film releases on HBO Max with little/no regard to Warner Bros.
