Damnit, forums are not for agreeing! Obviously there's some veiled argument/flame/mortal insult in your seeming concordance of views! :)
That being said, yes, I agree that "Apocalypse" in the title these days is going to conjure some Mad Max associations. But I think the more interesting question is do you want to try to push that word into some new associations, and/or use them to illuminate the "apocalyptic" traits of D&D? (e.g. "Oh, huh, I was expecting the Humungus and Orc Warg Gangs terrorizing halflings with boomerangs, but you know what? Even 'normal' D&D has a lot in common with that kind stuff. Who knew?). That's probably an overly ambitious aim for an RPG title, but I think worth thinking about.
