The Internet is buzzing with multiple reports that there is a new Nintendo Wii revision which blocks all current Wii mod-chips.
Apparently, the drive controller chip has been completely removed and Nintendo has combined the older D1A and driver controller chip into one which is called the GC2-D3.
Therefore, a big space has been left on the motherboard (pictured below) where it used to sit. More pictures and analysis is available at CNGBA (linked above), and to quote via rough translation:
In December 2008 the first major Wii platform, which is available in the market the latest version of the Wii console has been great changes have taken place in-house. The original D2x with the master chip at the bottom of the D1A into one chip, into a GC2-D3!
This means that all direct-reading all the chips can not be directly used in the new version of the Wii console on. Hackers have also re-examine the GC2-D3-chip pin definitions, and then modify targeted direct reading of the bridge chip approach.
We speculated that the new version of the Wii is currently using only soft approach to achieve the break to read CD-ROM version of the D (soft-mod on the situation detailed http://wii.cngba.com/wii_pj/2008111956812.shtml).
