The one team member that we know for sure stayed with Bungie is the guy or gal who names stuff. Halo had the greatest names for stuff (mostly ships). Pillar of Autumn. Forward Unto Dawn. In Amber Clad. UNSC Say My Name. I feel like the same dude or lady is now hard at work coming up with wicked names for Legendary's and Exotics. Personal favorite (although not weapon itself) is Super Good Advice. So bad ass.
