I don't like the suit, but the suggestion that the photo is at all dark, brooding, or somber is so strange to me. It's like we are getting another desaturated image of Superman, bathed in rain, with Cavill pulling his "I've been constipated for a week" frown:
The vibe I get from that reveal photo is "stoic" which is perfectly appropriate for a Superman facing a major crisis. Even with Reeve's version, everyone would think he was psychotic if he was flying around with a smile on his face during the cataclysmic third act of STM.
Also if there is a clone in this film and the plot involves Lex trying to turn the public against Superman. I could totally see there being a moment where he has been captured, de-powered, or what have you and this is him getting back in the fight after that. Hence why Supes seems to be getting dressed in a more terrestrial fashion.
