Yeah, I have original pressings of Piece of Time and Unquestionable Presence, then the re-release came out. It kinda sucked, but at least I found them collecting dust in some boonie record shop and did not have to overpay for them. The same thing happened to me with Disincarnate's DOTCK.
Still though, it's not all bad. The Atheist reissues were very good, after all. I bought the set on vinyl and, needless to say, I'm very pleased with it.
My hope is this new Gorguts set will also have a vinyl reissue.
