Additionally, The CW announced plans to feature a two-episode musical crossover with Supergirl and The Flash this fall, which will air after the four-show event.
The following year, The Flash and Arrow combined forces in order to introduce the second spinoff series, Legends of Tomorrow.
But, Arrow-verse producer Greg Berlanti has offered an update on the musical crossover and teased upcoming announcements.
I can’t say yet because we don’t have a deal yet, but I did speak to someone we’re really excited about.
