R-Rated Ender's Game?

Is it possible that Wolfgang Petersen is planning for an r-rated Ender's Game movie? It looks that way, according to MTV.com:

Now that he's done treading water with "Poseidon," director Wolfgang Petersen is turning his attention to "Ender's Game," a passion project he envisions as an R-rated version of one of Hollywood's most successful franchises. "I think 'Harry Potter' was inspired by 'Ender's Game,' " Petersen insisted, citing the 1985 sci-fi novel he's adapting.

Petersen cites "Potter" and the ultraviolent Japanese cult flick "Battle Royale" to give an idea of the tone he's leaning toward. "It's one of the projects at the top of my list of what I want to do next. I've been involved with it for quite a while," Petersen said, crossing his fingers. "We're getting another script for it in a few weeks, and then we'll see what we can do with that." ...
