I'm with Lax on this.
I fully understand what you're saying,and i hope their new album won't be a 'happy' one.
I love their darker side,SfAM,ToT,Awake,DT etc.
The atmospheres they create, the more emotional and dramatic material, needs some majestic music,
which isn't the case with 'happy' mood.
I feel you man,but we can only hope for that tone.
