Maybe someone like a Guillermo del Toro could do it, but it would need to be rated NC-17 for violence to be anywhere near true to the book, and unfortunately most big movie chains in North America refuse to distribute any NC-17 rated movie.
I just read Ender's Game recently, and I didn't find the violence anywhere near NC-17 level. Both of the instances where important characters die occur in very quick fashion, and you don't really understand what's happened until it's explained after-the-fact. The Battle Room scenes are brutal, but no one is permanently injuried or killed. The nature of them being a game removes a level of intensity from the violence. And the final war is entirely abstract (even Ender doesn't understand what's happening).
What is problematic for it is that all of the violence involves very young children. Not only will that make studio heads, the MPAA, and audiences squeamish, but casting child actors who can perform it believably will be an almost impossible task.
I liked the book, but if it is adapted to film I hope they cut out the entirety of the subplot involving Ender's 12 year old brother plotting to take over the world. That was just kind of dumb.
