If someone were to find a software exploit why should he release it when there's barely any good games and Nintendo could just patch it? Look at the PS3, they released a hack and everyone's still stick on firmware from Jan 2011. The only games since then that you can play on a modded PS3 have to be individually cracked by Paradude. If I was sitting on something I think I'd just keep sitting on it. Or would you say there's good reason to make it public?
