At first I was going to post my predictions for the band's next album, but then I stopped and pondered exactly what it was about Opeth that made them my favourite band.
I discovered that it's not their inventive riffs, beautiful dynamics or anything else that characterised Opeth and sets them apart. It was actually the fact that they never produce the same album twice - and don't let trends, record labels, producers, money or any of the potential pitfalls of the music industry influence their work.
As abcdefg said, I think we should all just drop our expectations and just trust Mike and the gang to continue making excellent music as they always have.
