User blog comment:MakeShift/A potential renaming of our wiki/@comment-4025272-20150112203552

According to the president of CBS, it looks like Supergirl won't be on the same universe as CW shows. If CBS and CW can't do cross-network, then it's even less likely another network can, so that kind of opens up the possibility for renaming after the CW.

I still like "Arrowverse" better though. Arrow is the show that created the universe. I don't think bias for the first show is a problem.
