This is good news to me. Earth-2 has been quite good, but unfortunately slow partially due to just how many characters there are. They have needed a true second book for at least year now. A weekly should do just the trick though the title World's End has me worried to be honest. I'm also not sure about the creative team. It doesn't feel on the same level as what we have for Batman Eternal or Future's End.
I'm currently not reading new 52's Earth 2, should I pick a trade or two up?
I think its one of the better series to come ou of the new 52 so I would definitely suggest giving the first trade or two a shot.
