One Year Later Explained... Sort of
Newsarama distills all the "One Year Later" explanations that occured in the WORLD WAR III specials: " Though some of the status quo changes have been covered in previous issues of 52, and still others will be covering in the Annuals of their home titles (as in the case of "Nightwing And the Proposal that Wasn't! - or - Hey, Everyone Says Dumb Things When The Think the World is Ending", for instance), many of these “OYL” moves occurred during an exceptionally busy week in the DC Universe: the week of World War III. We’re going to take a light-hearted look at a number of characters and see what facilitated the changes that we saw (and covered!) fifty-some weeks ago through the prism of the four WW3 specials."

I got 'em all, but was rather underwhelmed. The 'gaps' they were supposed to 'explain'? Hardly!! The Supergirl stuff is still confusing... Donna Troy, Nightwing/Jason and Batgirl are not even explained, even though they have panel time. Terra is senselessly killed so Didio can do his 'old mask-new face' trick again. ONE YEAR LATER has been horribly, horribly executed. SECRET WARS did it better over 20 years ago.
