So I guess to start let’s take a look at the other things we know are facts:

All the main cast from Man of Steel will return.
Batman will be in it, played by Ben Affleck.
Wonder Woman (Or at least Diana Prince) will be in it played by Gal Gadot.
Zack Snyder will direct.
Chris Nolan will produce (along with about six others including both Nolan and Snyders’ wives).
David S. Goyer will write it
It comes out in 2015 (the most jam packed year in movie history apparently).
The Flash is probably in it, but has not been cast.
