Most of the fuss and hype you'll read online will concern DC's Countdown book and the mini series stemming from it.
But a few years back, when I first read Alan Moore's brilliant Top 10, there was a promise at the end for an OGN called Forty Niners, that will take place a few decades earlier in Neopolis' (the city in which the series took place) history. That book was supposed to be published "next year" several years ago. But never mind the wait. It's coming now, and seeing Moore and Gene Ha's workin on Neopolis again is just as exciting now.
Of course, what I REALLY want is for Top 10 to come back as regular series. But this'll do in a pinch. This'll certainly do.
