Two interesting details come from the discussion in that:
1) Cavill is asked when the last time he wore the Superman suit to which he replied when they filmed in New Mexico. It's thought the New Mexico shoot, which took place near the end of filming, was for Wonder Woman's home of Themyiscira. So it's possible we'll see Superman with the Amazons in some capacity.
2) Henry Cavill is also asked how badly he hurts Batman in the movie, with Cavill replying, "Unfortunately, I can't say anything about that [laughs]. I wish I could. Believe me." The interviewer then mentions "a firm hand shake," with Cavill confirming: "There is firm hand shake at some stage. Yes."
"Batman v Superman: Dawn of Justice" has a March 25, 2016 release starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter and Tao Okamoto in new character roles for the film. Justice League is to follow directed by Zack Snyder as well.
