It's Offical... the Iron Age Superman is DEAD... Long Live the Post-IC Superman!

Is it? My understanding is according to Dan Didio is that it's still the current Superman origin, post-IC.

It is not. Kurt and Johns don't want to give it all away at once, instead giving it to us in bits, each bit contradicts Birthright.

I am sure that you could make a nice long list if you wanted to.

Frankly, I find it hilarious that of all the classic Superman elements that have been reintroduced, all the talent placed on the book and all the reaffirmation of Superman's classic identity, it's a cover with CHECKS ON IT that makes some people realize we're in a new age? Wha - ?

The moment of realization for me was when Superman and Adventures of Superman were merged back into one title.  Given that the Iron Age was launched with the title being split, I think the merger is a good official cut-off point for its end.  The symbolism of "Superman" (both the comic and the character) being messed with, but then repaired, fits well too.
