I doubt the Arbiter will do battle with chief but If they did I think it would be cool to have a choice of who you wanted to battle.
Think like all the missions lead up to this final conflict after Arbiter has dealt with Truth, and Chief kills Gravemind (possibly Cortana as well. You kill a A.I by pulling the plug on it's ass) Then the two make their way into the Ark and kill Brutes, Jackals, Drones, flood and anything else in their way seperatly and with marine/elite/hunter/grunt support.
thousands die in the Ark on both sides then in the middle of combat the Arbiter stops and realizes that he his fighting side by side with a human who has killed hundreds of his brothers and now leads his remaining elite brothers to their deaths.
Arbiter slashes a plasma sword into the chiefs marine buddies (possibly Jhonson even) and when the cheif realizes what happens he picks up a neaby dead gold elite's sword. The two become locked in the first battle where the swords actually clash and clang together (the halo 2 swords can't simulate a real sword fight but they should be able to in H3). The two fight and their battle goes all over the place as creatures from all sides die around them until the two make their way to a chasm (huge hole).
If you could chose the character you play as (I would be the cheif) the fight culminates in Arbiter being stabbed fatally and being kicked off the cliff into the chasm. Master Chief then goes back and finishes the battle for the marines and stops the ark's activation and/or closes the ark so the marines and himself will survive the blast.
If you played as the Arbiter you would kill te chief and when you stab him a cutscene plays where Arbiter knocks his helmet off thus revealing his face.
Then the same ending happens except you go back and kill flood/loyalist covenant/marines and then take over the earth after you either stop the blast or let it go.
How cool would that be?
