Devin Faraci from Badass Digest, mentioned on the blog that after hearing the recent rumor that Wonder Woman was going to be of Kryptonian decent, many multiple sources, told him these were incorrect.
I don't know much about Badass Digest, but personally it holds the same credibility than other movie sites that ran with the news that she was going to be Kryptionian. Personally I rather keep the two franchises separate in terms of origin story, Wonder Woman has so much history that will make her an interesting character on her own in this new shared universe that she doesn't need any help from anyone else.
As Amy Adams mentioned today on multiple reports, the script for Man of Steel 2 (Batman vs Superman) is finished and filming for the movie will start soon. From this we can expect that there will be many more rumors and actual news regarding the movie, hopefully most of them are actual facts that will get us more excited for the sequel!
