So according to one of the users on Absolutepunk, they are still aiming to get Cannibal Corpse and BTBAM to coheadline this, and he also mentioned Job For A Cowboy, Obscura, Skeletonwitch, and Last Chance to Reason. That, combined with a few other rumors that we've seen, and I could see next year's lineup looking something like this, assuming all the rumors end up being true:
Between the Buried and Me
Job For A Cowboy
Last Chance to Reason
*Vacant Spot* (Maybe to vote for the opener again?)
Don't take my word for it though, as i'm not sure how credible this is, but if next year's lineup looks anything like this, my ass will be there.
