Batman gets kicked out of Gotham?

Seems like there's alot of fuzz going around Batman today. Well, here's another fact:

It was rumored that New Orleans could pass off as Gotham City for Christopher Nolan’s follow-up sequel to The Dark Knight.It’s been confirmed.
CinemaBlend reports:

We reported back in August that Warner Bros. was considering shifting the majority of principal photograph on Batman 3 to New Orleans, abandoning Chicago after filming the majority of the first two films there. Now Superhero Hype has confirmed the rumor, adding that shooting is set to begin down South starting in April.

Well, hopefully there wouldn't be any flood or otherwise we gonna need Aquaman!
