I believe them, based on their main songwriter coming back into the fold.
FYI, he wasn't on Shadow Mechanics or that album with the goatse album cover.
That was my initial reaction, and the interview seemed entirely genuine. My only concerns are:
-They come up with too much material and forget about quality control, or try to stretch an EP into a full length
-Modern production standards suck the life out of their unique sound, assuming they do return to the style of the debut
-The vocals are either far too polished or far too hardcore sounding (the live vocals didn't have much depth)
Of course the above could easily be said about any death metal band attempting a return to its roots.
