Revolz wrote: Yeah. but this is Arrowverse wiki not "Earth-1 DC CW's wikia". Earth-2, Earth-3, Supergirl and 1990's Flash was confirmed in our multiverse. The reason we have earth-2 and 3 because they were elements established on an Arrowverse show. While we saw shows from other universes briefly, nothing on them were really established other than cameos. As for the SG crossover, it happened on a non-arrowverse show. Again, we aren't merging quite yet but it'll be considered after the big crossover, even though they aren't supposedly merging earths.
