When it was revealed that The CW had passed on Supergirl, a lot of fans were disappointed as it meant they didn't have an epic "Arrow vs. Flash vs. Supergirl" crossover to look forward to next year! However, KSiteTV have come across a very interesting tidbit in the latest issue of Entertainment Weekly which indicates that the three shows will still take place in the same universe and that a crossover is possible! "Later in the afternoon at his other office on the Warner Bros. lot, Berlanti meets with fellow producer Ali Adler and Oscar-winning costume designer Colleen Atwood to go over looks for their upcoming revamp of Supergirl. The show will follow 24-year-old Kara Zor-El, Superman's cousin, and with a twist that that could melt fanboy brains, Berlanti says it's possible this Supergirl could enter the worlds of Arrow and The Flash." Greg Berlanti is a producer on both Arrow and The Flash, and is developing Supergirl at CBS with No Ordinary Family's Ali Adler. If anyone knows about the possibility of a crossover, it's him, so start getting excited! What would you guys like to see from a crossover between the three?
