It seems there is a new Xbox RC4 key

Is packaged same as the SE Green but is standard black case with JAP S type controller

Just released in Europe - machine frags with current bios's / mods

Motherboard looks identical to v1.2

As soon as Xecuter get their hands on it you can expect to see an "X3" bios for that version of console shortly after.

We will of course confirm the RC4 (or possible other) change as soon as we see the board ourselves but is confirmed from three reliable sources now.
