The rumor has resurfaced in a Korean webzine that Wonder Woman will be a Kryptonian in the upcoming BVS. Read here.
Firstly, why should even the least fanatical WW fan, like myself, go to see a movie about a Kryptonian Wonder Woman, who isn't the mystical warrior we love from the 70s TV show or the comics? I won't.
Secondly, I think the writer has not made a clear distinction between spoilers and speculation, ..and it seems what we have here is speculation. Nowhere in the (above) article does it say that Zack Snyder or anyone else associated with BVS has said that Wonder Woman will be a 'genetically modified Kryptonian' in the upcoming movie.
Nowhere.
