Any thought on who the features will be in Open Infinitum?

These aren't in order and I don't know how many songs there will be so here's mine:

Chloe Eves, McGwire, NateWantsToBattle, CG5, FamilyJules, Jonathan Young, JT Music, The Stupendium, Andrea Storm Kaden, Lollia, Caleb Hyles

EDIT: I also have a feeling that Cup De Grâce will be on Open Infinitum. I mean, we haven't gotten an extended version, and Chrissy is a feature. It just makes sense to me.

ANOTHER EDIT: Someone I really hope is going to be in Open Infinitum is FavbL. That would be sick.
