I agree if this was just a superhero promo like it was at first that makes sense but it deliberately mentioned a crossover, and didn't include any part of Legends (which isn't a part of the crossover). I think its pretty likely that it will be an Arrow/Flash/Supergirl/Black Lightning crossover since that's what we saw in the promo. It also makes sense that Legends won't be in it because Black Lightning will.
