Personally, I think we're past the Iron Age, or at least past the 'disaster area' of the 90s (Death of Superman, Hal Jordan goes nuts, Aunt May dies, Aunt May isn't dead, Little May dies, Mary Jane dies, everyone dies, etc). DC comics seem more epic and iconic these days (Return to the 'base' JLA members, churning Elseworlds like a machine), and Marvel is busy playing with their Ultimate Aglhblhgalhga to get younger people to read the comics or something. Oh, yeah, and the -movies-. Dunno how the movies figure in.
Spawn, The Great Boogie Man Of The Modern Age of Comics, faded into... well, fadehood.
So what is the current Comics Age? Ice Age? No idea.
