SPOILERS TO Earth One.
So as the Ultimate Batman story, EO did very well in introducing new versions of Bruce, Alfred and Gordon that would be easy to digest for the Nolan's audience, and if you've read the book you know that Riddler is the villain of volume 2, and that's awesome, but it makes me wonder when will Johns introduce the Joker, Batman's most well known enemy and a sure crowd pleaser, and Ra's Al Ghul, pretty much his Moriarty in the Nolan fans' eyes (those who don't also read comics). Not to mention the Earth One Talia, Harley, Catwoman and Two Face and Dr Strange (who I was kind of dissapointed not to see in Vol 2 as his first recurring villain).
It's kind of exciting to see How Johns will reimagine them now that he has nothing but his imagination to stop him, is almost Batman Begins all over again!
But I still wish Brian Azzarello and Eduardo Risso (with covers by Lee Bermejo) were doing this
