You can do this, 343! Just bring back the guys who made the series what it was!
Martry is heading up his own studio right now - Highwire Games - who are working on their own game right now. Joe works for MS studios, he worked on Re-Core and is doing some Halo novel stuff
Maybe just for personal input, but for them to actually work on halo? A Spartan can dream.
Eh. Neither feels particularly necessary. I don’t think their presence would hurt, but if the Halo Infinite trailer is anything to go off of, whoever is handling the soundtrack seems to have nailed Marty’s style down, and I’d say their writing team has solid potential that was just wasted or ignored with Halo 5.
