If you really want to argue they saw early art and made up a story around it, fine, but what use is that to anyone? There's no benefit to this bullshit and the Lindsey Wagner casting as a love interest was the only long shot. Further casting claims by the same person of Ryan Gosling, Emma Stone, Emma Watson, Idris Elba and others don't do it any favours.
Leaks don't usually tend to do things any favors? As I said, I wouldn't worry too much about it, since this seems to be from an early point in the development, so there will be a lot of inaccuracies, though I could definitely imagine a lot of the overarching themes/concepts do still exist in the game in some form.
