You've probably already seen the cover to JUSTICE LEAGUE #8 by Jim Lee. Apparently Green Arrow is coming after the Justice League. He doesn't look too happy. It might be because he's never been invited to be a member of the team. Check out that cover here if you haven't seen it already.
This time he looks a little happier. Maybe they did finally invited him to join the team. But DC also included a quote from Batman:
We all know what happened when we let someone ELSE in to the Justice League. It ended very badly.
What the heck does that mean?!? Guess there's still a lot we don't know from the five years between the first arc and the current.
JUSTICE LEAGUE #8 is on sale April 18, 2012.
