Crowded in MoS 2 much???

On the Eve of the Man Of Steel Blu-Ray, a lot of information ( rumors ) have been coming out about the Man Of Steel 2 movie a.k.a. Batman vs. Superman or World's Finest. One thing that we do know Batman who is going to played by Ben Affleck and Superman is going to be played by Henry Cavill will be in the movie and that is all we know. The internet over the last couple of days has been buzzing with news of which new DC character is supposedly be in BvS. Nightwing was one of the characters that is supposedly to be in the movie. I think this would be an interesting choice considering what happened in the end of "The Dark Knight Rises" movie. I would like to see how the studio would develop the character and whether or not they are going to reference he (Nightwing) was once Robin. The other character that is said to do be in the movie is Wonder Woman. As far as whether she is going to have an important role in the movie or not is still remains to be seen. It will be a big step in the right direction, giving one of the notable characters from DC her own movie. Another superhero who is supposedly to be in the movie is The Flash. What is DC trying to do with putting all of these characters in one movie? . . . . . .  . . Ahh yes the long awaited Justice League movie. Now people might ask themselves why is DC is doing the Justice League movie this way and not the way Marvel did it when they did the Avengers. My answer to you guys is to look at the comics, especially the graphic novel Justice League "Origins", written by Geoff Johns. In the graphic novel, the superheroes met one by one until they formed "The Justice League". If this is the case, I have a couple gripes about it. First they are going to be missing some key members like Green Lantern, Aquaman, and Jon Martian Manhunter. ( Maybe just maybe Martian Manhunter will be introduced to us in Justice League Dark).  Maybe the reason they did not add Green Lantern yet , is because WB would like to see the response to MoS2 and if it does pretty well. Is the movie does well WB will find some way to bring Green Lantern to the Justice League.
