As I have said, numerous times, before, there are a few conditions on which exploits will be released:
1. Nintendo patches a bug we're using.
2. We develop another stockpiled exploit, allowing us to release one (this is tricky, though; Nintendo may fix unreleased bugs too, so we have to play a psychological game to determine which exploit is the most advantageous to release).
3. We come up with a method to prevent updates and prevent bugs from being patched. crediar's firmware spoofer or even a boot time exploit that patches out IOSU's update ability would be examples of this. Even then, we still have to keep in mind that we could release an exploit, it will get patched, and then someone just joining the scene may be locked out. So we don't necessarily want to do this if other exploits don't exist first.
Right now, we have a browser exploit that Nintendo hasn't patched and a kernel exploit that Nintendo hasn't patched. We're currently ahead of them, and don't want to lose the advantage. Currently, developing more permanent attacks or more exploits is worth it, and that's what we're working on.
