Per the CW presentation at the TCA: https://deadline.com/2019/08/black-lightning-the-cws-crossover-crisis-of-infinite-earths-1202660768/ https://www.ign.com/articles/2019/08/04/arrowverse-crisis-on-infinite-earths-crossover-batman-bruce-wayne-kevin-conroy The schedule for the Crisis has been set. Kevin Conroy as Bruce Wayne from the future and characters from Black Lightning will appear for the first time in the Arrowverse. Kevin Conroy, of course, is the voice of Bruce Wayne/ Batman from Batman the Animated Series and Batman Beyond and others. Supergirl: Sunday, Dec. 8 at 8/7c (special time) Batwoman: Monday, Dec. 9 at 8 pm (special day) The Flash: Tuesday, Dec. 10 at 8 pm Arrow: Tuesday, Jan. 14 at 8 pm (special time) DC’s Legends of Tomorrow: Tuesday, Jan. 14 at 9 pm (special episode) I wouldn't think Arrow would end in the middle of the Crisis so I assume there will be at least one more episode following the Crisis, That last Arrow episode better not be "RIP Oliver Queen" Arrow probably wont air a new episode the week of December 8th. Based on where the Flash is airing I would say the big cliffhanger over the holidays is " Flash Disappears In a Crisis" with Barry seemingly dying. The date of the newspaper in The Flash's Time Vault will change to be December 10, 2019.( Good promo for the Crisis) They should air this like they did "Crisis on Earth X" where it was one long movie and you almost couldn't tell which of the Arrowverse shows it was supposed to be on.
