Like Derek said, speculation is useless when it comes to these guys. What they mean (I'm sure) is that the album is going to be more like the pre-ATS in that they are returning to song-centric writing, making good songs and putting the ones that work well together on the album as opposed to writing one cohesive 45 minute track.
I'm excited to see what's coming. It feels like this is the logical progression (on the timeline) for them. Take what they've done musically and lyrically through all of their divergent song writing and make it one with their original sound, thus creating the sound they've been searching for all this time.
PS: Screaming feels good. It takes a while to teach yourself how to do it without destroying your voice, but once you've got it, it feels amazing to get a mic in your hand and just belt in front of an audience full of energy.
