As Graf_chokoloko already promised he came up with a new payload for PS3 development and reversing:

The payload is published on github: http://github.com/grafchokolo/psgroove

As he is already known for big understatement, Graf_chokoloko only advertised this with a comment on the xorloser blog.

His comment can be found here: XorHack v2.0: The Updated PS3 Exploit Toolkit « xorloser’s blog

I am quite sure, this could be interesting news for some people...
