I don't think Redcloak will die in the fight, and I'm hoping that Hinjo won't. I don't see Redcloak using the Hobgoblins to cover his retreat, because if he was willing to kill that many, he wouldn't be there now and soooo many things would be different.

An interesting twist, that almost definitely won't happen, could be Durkon's death, making the whole resurrection thing much harder.
