Wes talked to me about this in the interview I did with him a few weeks ago.
If the lineup that's currently being rumored is true, The HAARP Machine will be on it because they are on Sumerian. Every Sumerian band has to tour with another Sumerian band.
Regardless, they are the first band and would get around a 25 minutes set. that's worth it for The Faceless and Fleshgod Apocalypse.
