New readers = lapsed comic book readers and marvel readers (who are indeed copping these comics when they come out per online polls at least)
I think they're deluded in thinking the general public will suddenly start buying DC comics by the truckload. Going digital is a decent start in light of tablet pc's but at the end of the day till they get into wal-mart and shit like that they're not gonna have a tremendous increase. They'd be lucky to get a 5% increase in sales IMO. I don't think this is going to work to lure in your cousin or girlfriend or best friend or brother into buying these comics.
JL was decent I like the fact that he compressed what would normally be 2 issues worth of story into an action packed comic. I hope this means they'll be doing 3 issue arcs at most. That's the best format around. Like really the tension between Bruce and Hal even in this new continuity is still alive as fuck. That was well played. Showing Vic's accident to the many people who don't really know Cyborg's origin means they'll be clear on the character. I like Kal-El already. Superman could always take them all down. Only Captains Atom and Marvel stand a chance.
