Check the Noob.com thread. Folks are entering numeric sequences on a teaser site and unlocking teaser images that are blurred (except for the Aquaman trident one).
So far 3 of 6 images have been found. We know its 6 due to a java script thing someone did. Aquaman has been revealed and his teaser image on that site is the only one unblurred and it has "3e" in it.
3=c
5=e
on the alphabet and at the bottom of Noob.com is "INJUSTICE" spelled with the corresponding numbers for each letter on the alphabet.
My guess is every character on the blurred images will be a reveal and as they get unveiled their images will unblur revealing more letters and numbers in each image that eventually spells Injustice.
So far the images are...
