Not really a teaser video or even a sneak peek, just a load of crap! The entire video just contains the costume of Superman and Batman and Batman/Superman logo.
The only part that is of any credible information is the on the first 4 seconds of the video that says “On April 20″.
So whats on April 20? Well, here is a tweet from Zack Snyder.

They are just building way too much unwanted attention on a movie that is to be released almost a year from now, moreover these stupid “teaser” is really annoying!
