Joseph Gordon-Levitt Playing The Next Batman After All And Snyder And Cavill Involved In "Justice League" Film Too?

Reports online are strongly suggesting that Joseph Gordon-Levitt is in meetings over at Warner to star as the new Batman in their "Justice League" BIG-screen movie. It's been rumored for ages that Levitt could be the next Batman in either a direct sequel to Chris Nolan's film series or crossover and enter into the "Justice League" film universe when it begins in 2015. 
Online sites were suggesting that Warner were going to clean the slate and cast a brand new Batman for both the "Justice" universe and the solo Batman reboot series, but now that may not be the case after all. John Blake could be Batman rather than go back and re-create Bruce Wayne again. 
Fans, including me, didn't like the idea of two Batmen and the same going for Superman, two different Supermen on-screen. Maybe Warner have listened to fans and thought, "Fuck it, let's bring back Levitt and keep him as Batman from now on."...........well hopefully, because this is just a MASSIVE rumor. 
Zach Snyder did though let slip that he and his Superman, Henry Cavill, could be apart of the planned "Justice" film after all, rather than the split universe. I would rather see Cavill come back rather than two different actors playing the same hero on-screen.............POINTLESS!!! 
When Snyder was asked about his involvement in the "Justice" film, he said, 

"I can’t really say anything to that, because that’s a big spoiler. I will say, yeah, they trust me to keep them on course."

He also added,

"I don’t know how ‘Justice League’ is going to be handled. Honestly, I don’t, but ‘The Man of Steel’ exists, and Superman is in it. I don’t know how you’d move forward without acknowledging that."

UPDATE: Hollywood.com have reported that Gordon-Levitt's reps have denied the rumor of him appearing in the "Justice League" film as John Blake. Reps have denied things before and it's turned out true though.
