What happened to Bruce Wayne? And are any of the old Villains in the new Batman and Robin series?

Bruce was hit with an Omega Effect in the Final Crisis, this sent him back to the stone age. He fought his way back through time. During his absence took over as Batman, thinking Bruce was dead. Tim Drake went on a hunt thinking Bruce was still alive, finding clues that he was right, takes Damian on as Robin, and that's where you're at.Joker is in the morrison run towards the end in a twist. You will see Riddler around, mostly in Birds of Prey, along with Batgirl, Oracle and Penguin playing the villain.
