Today, I found the Wii's disc tray emitting blue light again. Nintendo has released yet another firmware update for the Wii, but it is mainly bug fixes. From the Wii message sent out:
"A new update for your Wii console is available!
This update will prevent your Wii console from locking up, which can occur when using the Internet Channel if you press RESET on either your Wii console or within the HOME Menu. This update also corrects some Internet connection stabability issues when using the Wii LAN Adapter from Nintendo."
I checked, and no extra keyboard support has been added. Also, the FLV video found here does not crash the Wii anymore. Another potential homebrew exploit gone. And as a side note, the Wii's still at 3.0x.
