*Superman's robots--not android replicas, but actual robot versions of himself, with an awesome inverted color scheme.
*The Super-key update. Honestly, so much more intelligent than the giant arrow-shaped key that points at his "secret" fortress.
*How casually Superman discusses all the awesome stuff in his place.
*How there's a sense of weariness and worry about Superman, but that he's trying to mask it from Lois.
*References to the Superman of DC One Million. Does this mean that One Million is no longer the official future history of the regular DCU, but is shifted to the All-Star universe? Or do they just have convergent timelines? Either way, cool.
*Lois's reaction to the news. Fan-freakin'-tastic.
*The Bluebeard/Cupid & Psyche plot. "Don't go in the back room," with a pleasant twist. It reminds me a lot of some of the older stories in the Showcase Superman collection, except that Superman's not actively testing Lois's fidelity.
Great issue. Can't wait 'til the next one!
