I think that, with licensing issues and debates between separate broadcasting channels, that CW DC shows will have its own universe, CBS DC shows will have their own universe, so on and so forth. I don't think that separate channels will mix together with their shows for multiple reasons. For one, it's damn confusing to have a mullti-channel crossover, even if the two shows originated in the same universe (DC Comics). Two, Supergirl will eventually have some Superman reference at some point, and with BvS coming out next year, everyone's favorite Kryptonian will be cinematically associated with the Dark Knight, and since CW can't use any Bat characters, it's unlikely that Supergirl will exist in the same universe as its widely successful CW counterparts. Third, there will probably be continuity errors between the two shows, especially if Supergirl is set in a real location, such as Manhattan or Los Angeles. What Arrow did with setting up Flash was genius, but how can they set up a show that is pre-destined for a Fall 2015 or Spring 2016 release date? It's too late at this point, so I say that Supergirl will most likely NOT be in the Arrowverse, and the same thing with Titans. Just a thought.
