During the Television Critics Association summer press tour this past Sunday, the President of the CW Network - Mark Pedowitz - announced to reporters that the network is hoping to add yet another show to the Arrowverse in 2020. Pedowitz would continue to confirm that the show will be set firmly within the Arrowverse, rather than Black Lightning, which has not had any connection to the other shows prior to this week's announcement that its characters would feature in Crisis On Infinite Earths.
As the show will inevitably debut after the mentioned event, the possibilities for what it will be are extraordinary. One has to imagine that fallout from this much-anticipated Crisis is going to have lasting ramifications for the universe going forward - akin to Endgame's influence on the Marvel Cinematic Universe - such as collapsing the multiverse into one earth, similar to the event's source material of the same name.
