Probably a sign of the times but it's hard to see bands really making as much of an impact in this day and age like they did back then. I think times might have changed too much.
You got bands like Trivium who spring to mind who could nicely steer the ship but in reality, who could really see anyone really doing what Maiden, Priest, Sabbath, Zep, Queen, Stones etc. did in their respective genres.
I don't think there's a definitive answer, time will tell.
