So maybe, we have two universes: DC CW Universe (Arrow, The Flash, Constantine, Vixen, DC's Legends of Tomorrow) and DC CBS Universe (1990 The Flash and Supergirl) who will crossed over in "Worlds Finest"!

It's a possibility, maybe 1990 The Flash and Supergirl are set in two different universes, maybe they are set in the same universe, I don't know.

What do you think? It's been confirmed to be Grant Guston's Flash to be crossing over. Not the 90's Flash. I don't explain very well, but I said that maybe the Supergirl universe is the same that the 90's Flash (because they are in CBS), and when 2014's Flash will crossed over with Supergirl, maybe there will be a crosover with DC CBS Universe (1990 Flash and Supergirl) and DC CW Universe (Arrow, 2014 The Flash, Constantine, Vixen, Legends of Tomorrow)
