I have heard that Carnifex is trying very hard to get on warped this summer, and Born Of Osiris are starting an online campaign demanding that their fans get them on Warped tour this summer.
MMI did a very similar thing last year... I'll now be almost shocked if BoO doesn't end up on Warped, and also a bit surprised if they don't bring After the Burial along with them. And holy shit, would've never guessed that Carnifex would try for Warped... I feel both bands Warped sets (if both get on) would be so much fun.
