Avenged Sevenfold has posted an updated on their upcoming plans and new record:

It has been awhile since we have shed light on our current doings. We have been focused on only one thing, writing and preparing to record what to me is our most personal and epic Avenged Sevenfold album. The reason is the fact that everything happening around us in the entire world might be a once in a life time source of inspiration and direction.

We have been harnessing every aspect of what makes A7X truly unrelenting and building off of that. I don't think we sleep too much anymore because of the excitement we feel while writing this album.We are also in the final stages of solidifying our production team, studios and engineers so that the second the axe falls and the album is written we will spend day and night in the studio until it is complete.

They released Avenged Sevenfold in 2007.
