If that was the case they probably would have just changed the date. Unless they wasn't sure what the new one was going to be but that's unlikely at this point. Also from what I understand about WB, they don't really care about speculation regarding release dates despite them being quick to make websites dispel the February 14th date that the radio dude tweeted. Honestly, fuck knows. At this point there's been so many rumoured dates that anything is possible.
