So, I was browsing the web and stumbled upon this article written on flickeringmyth.com, where the author manages to get the past scripts written by David S. Goyer, Chris Brancato, and Greg Berlanti/Michael Green/Marc Guggenheim. There are three scripts, as we only see the first intro page of each script, but the author of the written article summarizes all the scripts of what happens through-out the written storyline.The last one seems to be linked to the Green Lantern movie, where they were news or rumor, I'm not sure, that they'll be the Flash and Green Lantern universe combination.
Here is the link to the article: http://www.flickeringmyth.com/2014/01/born-to-run-bringing-flash-to-screen.html
P.S. I didn't know if someone else stumbled upon the scripts or the article before, I did manage to first search the forum but didn't catch anything, so i apologize if someone has already started a topic about these scripts before.
