Unrepentant DM Supremacist
I wouldn't count on him playing. Tell him upfront what you're interested in running. If he hates Eberron and prefers a more classic feel, then he probably won't want to play. He'll likely be a problem if you're not honest with him from the start.
Either that or offer him the chance to DM a more old-school campaign if that's what he wants to play, and if your group is interested in multiple campaigns (and the other players don't mind what he's running either).
