Does anybody know when avenged sevenfolds new album will be released?

I want to know because I have been a fan of them for 4 years now. The new album is the one with "not ready to die", on call of the dead zombies Not Ready To Die was released as a single, It's not on an album. It was made for Call Of Duty.

And as for the new album, Avenged Sevenfold is constantly writing music. And they will probably head back in the studio within 2013 to record a new album.
I would expect a new album in 2013 or 2014. But they released Nightmare not too long ago, and it was highly praised, so they want to bask in the glory of that album for a while.
Don't expect it too soon though, writing and recording an album takes a long time. So just be patient. But I would expect an EP or more single's to be released soon.

Have a great day!
