I remember for a while DC seemed hellbent on making Weekly Comics a thing. 52 was probably their best shot at the concept. Countdown was the sort of mess you wish you could forget and I have almost entirely forgotten Trinity. DC wants to give the thing another go with Scott Snyder this time helming the project alongside a team of writers that include James Tynion IV, John Layman, Ray Fawkes, and, most interesting to me at least, Tim Seeley. Art duties will be handled by Josh Fabok, who I speculated would find a major project when the switcharoo with creative teams on Detective was teased a while back. Other artists will likely join him on the project soon. (source)
All of this is of course in connection to Batman’s 75th Anniversary. You can expect big things for Batman soon. In conjunction with this announcement, DC stated that the upcoming Detective Comics # 27 will be a 96 page epic featuring work from some pretty heavy hitters including Frank Miller, Paul Dini, Brad Meltzer, and Neal Adams with art provided by Greg Capullo, Jim Lee, Chris Burnham, Mike Allred and others.
