I'll go first I guess.

I think we'll have an arena tour starting late summer going into fall 2017.
I'm not expecting any dates in the spring. Summer amphitheater could be possible but it all depends on when the new material is released.
I have no clue who would handle bass/guitar duty but I'm pretty sure the rest of the lineup will be the same with Fink, Cortini and Rubin. If Rubin is busy with another project, I'd expect Freese to come back.
