At the London premiere of the Man of Steel, Zack Snyder spoke about a specific Easter Egg in the film.
Some time in the movie, Wayne Enterprises is mentioned, and Absolute Radio caught up with Zack Snyder to get his thoughts on that, with mention of the Justice League movie.

Snyder also goes on to say that it is a nod to Christopher Nolan for all his amazing help as producer and what he has done for the movie.
