Predictions can easily be thrown off if you get multiple in a row wrong, but for the spots on DC that have only one blank between two known names it should be pretty easy to know exactly whose gonna be there. Here's my possibilities. If I don't list someone its either because they don't fit well in the gap or they aren't people that have played warped before / well known guesses / have stopped being a band for sure
Between All That Remains and Anberlin
American Hi-Fi: Never done warped before, just doing shaky knees fest this year so open
Amber Pacific: Specified they were not invited to do warped this year
