and of course hes in MCU which is just absolutely huge. and hes working with Burton again
and now studios are frequently doing the long belated ''legacy' sequels (TFA, Creed, Top Gun 2 etc) and even ignoring bad sequels/reboots that came before (Halloween'18, Terminator 6, Ghostbusters 3, Robocop 4) and WBros are now seemingly doing sideline unconnected DC 'one shots' (Joker) plus as the article states 'Logan' was hugely successful in showing an older version of the character (which was also less connected to the established series via plot, setting, tone, rating) and this could be a sort of Batmans version of Logan.. incorporating Batman Beyond and The Dark Knight Returns (some of which TDKRises and BvS have already incorporated) the way Logan did with the Old Man Logan comic
so where just a few years ago a Batman 'III' seemed impossible/unthinkable, now it could be entirely possible (esp with Keaton an Burton reuniting for Dumbo)
