That'd be disappointing compared to last year, but I'd still go. I feel bad for LoG, since FFDP played before them in 2010 and then after them in 2013. Also, CC on the main stage just feels odd. But looks solid, and then I could see Gojira.
Also, if that is true, how the fuck has Testament not gotten on Mayhem yet? Not counting the few dates they did in 2011. With their new album out now, they'd be a perfect rotater, and they're (essentially) one of the few non-repeats.
