Slipknot - i doubt it. after all they've said they are making another record and from this interview it's only the percussionist who has any problems, so if he left i'm sure they'd find a replacement. so at the moment i think Slipknot are staying around (woo!). if other band members say similar things to clown in interviews maybe that opinion will change tho. Megadeth-well it's obvious Mustaine doesn't have a problem changing line-ups. maybe he'll take Megadeth in a NIN style direction in so far as he is the only permanent member, who writes all the music/lyrics but for live shows will get people to help out? i don't really know much about Megadeth so i can't really comment.
