If Anders kicked Swano out because he could not commit to touring, then what makes you think Mike Akerfeldt will be doing vocals? Opeth Practicaly tours constantly, and when they are not touring they are writing, and when they are not writing they are on break. I dont see him returning, I can see Pete returning maybe, but who knows lots of young blood rising in the scene these days it could be nobodys. If Mike does do it or did it, Its probably just session work and no tours involved. I could be wrong about this sure, but if it does happen, Ill be shocked because the first Bloodbath album dominates so much.
