As Clark Kent and Lois Lane work in the Daily Planet, a big world wide newspaper, then this is the perfect opportunity to expand the universe with big selling newspapers such as:
JOKER TERRORISES GOTHAM
BATMAN: HERO OR VILLAIN?
GOTHAM MOURN DEATH OF DENT
WHO IS THE BATMAN?
HUMAN JOINS GREEN LANTERN CORPS!
ONE OF US JOINS ALIEN POLICE FORCE
BRUCE WAYNE RETURNS
OLIVER QUEEN RETURNS
Other places where Easter Eggs can be placed is in off chance remarks. TV screens featuring the news could be showing the events that take place in "Green Lantern" or "The Dark Knight" and saying how the world is filling up with heroes. Also something along the lines of this (Superman just revealed himself)
Jimmy Olsen: We need to give this guy a name, like Batman.
Jimmy Olsen: This guy looks powerful cheif, like stronger than Green Lantern powerful.
It has to be Jimmy Olsen with the easter egg line, he is like a fan inside the movie watching all this unfold and loves it all. We get a sense of what that world is like through him.
There are plenty of ways to include the rest of the unvierse but will Nolan do it, that is the question. Time will tell, hopefully he will. One person who I am most desperate to see on the big screen after Superman is Martian Manhunter. He is one of my favourite characters and could be like Nick Fury, obvserving all of the heroes that are emerging on Earth knowing that a dark threat is coming, Darkseid! If you want a full Justice League movie script I wrote that was Darkseid invading Earth, contact me and let me know with your email address. Thanks.
