Just a question. One thing I want to know is what happend to the Arbiter after the events of Halo 3. Will he make a come back at some point?
What does everyone else think?
Read halo escalation then.

Yes.
343i have stated they have plans for him 
If I am correct hes in Grasslands. And Escalation I hear hes in also. So I believe post halo 3 hes already making quite a splash.
