I've heard the material Killswitch is working on is extremely heavy and not much like they're other shit. So that should be interesting to hear.
The Used said their new album will be a lot more raw and heavy than their previous two. It's called "Artwork"...sadly nothing from it has leaked yet.
30 Seconds to Mars should be something to look foward to, they're always pretty solid.
I'm also hoping to hear some new shit from Soilwork and Dark Tranquillity.
Dave Mustaine has a mega hard on over their new album, so let's see what comes out of this one. Their first work with Broderick, hopefully Dave allowed him to have some imput on the songwriting.
