There has been a very interesting technical discussion in our forum about the new v1.3 xbox.

People close to Team Xecuter, Team Xodus aswell as 'independents' have worked together and tried alot of different possibilities and came to the conclusion that the MCPX-code didn't change. (exploits like the RC4-check bypass (used in multi-version bioses) have not been removed by Microsoft, they also didn't use a better hashing algorithm).
This means no new RC4 key must be found and no new bios must be made.

Ubergeek (Team Xecuter) succesfully booted his v1.3 xbox with a X2 4976.02 bios flashed on his TSOP. (he replaced the original 256k Winbond TSOP with Amic 29F040 512k ('cause he had problem to write on the winbond chip) ... that's also a nice hack )

The problem on the new xbox version are the LPC points. "D0" is still there and doing it's work but Team Xodus pointed that Microsoft changed something with 1 of the LPC points: LFRAME (pin#3) is 'gone' (it's not connecting with the MCPX anymore).

Homebrew 29-wire modchips have not been tried yet, but it's very possible these will still work.

Now that they know the exact problem - they can try to work on a solution.
We'll report more as soon as there's something important

You can also read the whole discussion here (please only reply if you have something important to say - don't ask stupid questions in that thread)

Also note that there's still no decent way to see the difference between a v1.2 and v1.3 ... we will try to find a visual difference as soon as we manage to find a v1.3.
