Time to clear the air again.

The following statements are facts:
- I have successfully compromised the Wii U's IOSU;
- The exploit being used works from 2.0.0 up to 5.5.0, but it obviously needs to be ported for each firmware;
- The exploit doesn't need PPC kernel access, so the new kernel exploit won't have to be released.

I want to do some kind of Christmas surprise yes, but take that with a grain of salt. I can't promise I will have the time to get everything ready by then and I'm not disclosing what will be released.
Keep in mind that releasing the exploit "as-is" is pointless, so it will have to be ported first and most likely obfuscated so it will take a little longer to patch. It's also worth noting that I will have to develop an easy way to block updates so no one updates past 5.5.0 by accident.

If you don't believe in anything stated above, that's not my problem. The best (and easiest) thing to do is wait and see.
