Update: There was no Batman Vs. Superman Super Bowl trailer, but DC has said Batman Vs. Superman news is coming in February.
The info comes from an advertiser analytics website, ispot.tv; they have it listed a 30-second spot for Batman Vs. Superman will be shown.
The Batman Vs. Superman trailer hasn't been confirmed by Warner Bros., and another rumor has it the Batman Vs. Superman trailer is attached to Jupiter Ascending this Friday, so maybe we'll get a 30-second Super Bowl preview followed by the full trailer.
While Warner Bros. usually skips out on the Super Bowl - there were no Man of Steel or Dark Knight Super Bowl trailers - perhaps WB wants to kick things up a notch as Batman Vs. Superman comes out a couple weeks prior to Marvel's Captain America: Civil War, which is essentially another Avengers movie.
Here is the screenshot with the Batman Vs. Superman trailer listed:
"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.
