Vibe and Katana? Well noone can accuse DC of not throwing crap against the wall to see if it will stick. Vibe I have no interest in right out of the box but Katana might be interesting if handled properly. And 52 varient covers for Justice League of America #1. Wow, thats just insane.
Didn't they learn their lesson with JL International? I would love to have a book about the characters from the seventies and eighties (pre-Detroit) that haven't joined the League. Hawkman, Atom, Green Arrow--then Elongated Man, Black Canary, Firestorm, Zatanna, the Martian Manhunter, Hawkwoman...am I missing anyone?
