I think the only time, or way Opeth will ever ''break up'' is if mike feels that they will, or are about to tarnish their name.
Opeth is mikes baby, hes not going to just throw the towel in. But forwhatever reason Opeth has a chance of ruining their integrety Mike will likely put a stop on the Opeth name because im sure in a few years a new generation of prog fans, or metal fans will look back at the bands of the 90s and some bands will still have a non- tainted legacy (opeth, tool, radiohead ect) but then some bands will have a tainted legacy for whatever reason (in flames, metallica ..ect)
But yeah aslong as Mike is still strong in opeth, and things are not looking to tarnish the name. i dont feel Opeth is going to break up at all...
and iv searched for tons of translators and every page i went to is terrible.
