I'm way less concerned about WW/SM happening, I think the films are really invested in SM/Lois. Lois is going to play a heavy role on the Superman side of things, and with everything else going on (the major one being the conflict with Batman, but also all the stuff with Lex, the founding of the JL, etc.) there really is no time for go for a love triangle. At least, I hope they're smart enough not to try to squeeze it in.
