Even thought the console ships with a "lite" version of Opera (the Wii Shop uses this) the general Internet Channel isn't yet live.
The good folk over at Wii Spin have received word that the software will become available later this month, at least in Sweden.
"The release date for Opera on the Nintendo Wii has been revealed on Nintendo of Sweden’s website. According to the site the browser will available for download on the 23rd December, just in time for Christmas. No word has been given about the release in other regions."
We'll let you know if we hear anything else.
