calm down kid, i never meant that people into extreme metal necessarely are into Opeth, you could figure this out by yourself, but i'll explain it to you anyway.
i meant that those involves into the so called "scene" are tho ones whe are aware if an Opeth record comes out, so, in other words, the universe of those that potentially would buy an Opeth record is related to only a few of the 9 million of swedish (but i believe that now, that wall is coming down because of the beautiful Damnation). and of course, the internet factor is huge, so the "Universe" is getting smaller and smaller.
