Alas! A new still (and bonus graphics) have been released from the upcoming Ender's Game film! Back in early December 2012, a single still featuring Harrison Ford as Colonel Graff and Asa Butterfield as Ender Wiggin was released, and we've been waiting ever since for one more visual morsel from the film's production. The graphics for the Battle School Team logos are especially good to see in detail!
Again, only one still was released, but this one reveals a lot more details and shows Hailee Steinfeld as Petra Arkanian! If you want to see an in-depth investigation of all the possible details in this one photo, click here for a really cool analysis.
