Ok, this is taken out of a piece done by Buzzfeed, where in a section of the article the president of the CW (home of Arrow and Flash) says in regards to a third show…
“There are discussions going on, but I can’t tell you what they are.”
Interesting, and promising. Now there have been rumblings about another DC-CW collaboration for a while now. Most notably the now defunct Wonder Woman show titled Amazon. There was also a show to be centered around Justice Society of America regular Hourman. Which has been very quiet, probably inferring that it hasn’t gone past the initial stage of development.
With the floodgates now open, and an established universe that currently has Arrow and Flash residing in it (and many more), it’s not hard to imagine another superhero getting their due. The only question is…who?
