Time will tell on that front, but we have a very cool new poster below which is definitely reminiscent of a similar moment in the "Flashpoint" event a few years ago. Meanwhile, the poster for Arrow features the Green Arrow being overshadowed by his supporting cast, but what's new there, right? Let us know your thoughts on these below!
