A trailer for season two of The Flash (and for season four of Arrow) really should drop any day now, but while we wait for that, we have a very cool new promo which gives us our first look at footage from the series. It's brief, but we get a glimpse at heroes and villains alike; however, no doubt the most interesting reveal is the Flash-Signal. That should be a very interesting addition to the show, but a little on the nose considering the fact that it's something so closely associated with Batman! Perhaps that's our first look at Earth-2? We'll just have to wait and see. What do you guys think?
