I hope that the new album will be very experimental, modern and innovative, with a huge amount of electronics and synth-keys and a lot of experimentation from the guitars.
However, I don't dislike a return of acoustic pieces, but I prefer an album that watches over and not in the past (but a song with electronics/acoustic combo could be very interesting).
Doesn't matter if prog (REAL "progressive" music), electrometal, experimental industrial, alternative etc etc. just something of fresh, live, innovative.
