Infinite Frontiers collapsed with the firing of Dan Didio. I think there have been ten reboots. There was the original Crisis, Zero Hour, Infinite Crisis, 52. Convergence, Flashpoint, Rebirth, Doomsday Clock, and two more I think revolving around the Dark Metal stuff going on with its villianous Batman.
Infinite Frontiers was the tail end of 5G where all the main heroes like Clark Kent/Superman were replaced by their kids. There was supposed to be a timeline and everything. Dan Didio got fired before that happened.
Geoff Johns is writing a time travel thing where new characters are being introduced as displaced characters like jay Garrick's daughter, Judy.
DC Comics right now is full of fan fiction writers made good so no one knows what the actual continuity right now is except for individual stories, and it's come out I think in Wonder Woman that Shazam has just killed Zeus and made Hera his replacement as the Queen of the Sky.
