I have realized that are plenty of blogs about who should take the mantle of Batman.  But seriously,  I  it is most likely going to be Nightwing because they canceled his issue, for now, which most likely means he will take the "take the cowl" until Batman returns and then i think Damian will take a more permanent role as Robin and Tim will take the role as Red Robin or something along those lines.  But who do think is going to be the next Batman? Its a big question...
