The Terra Soft Solutions site has been updated to announce that the Yellow Dog Linux distribution will be available for the Sony PlayStation 3 at console launch:
YDL v5.0 is slated for release mid-November with support for the Sony PS3 first, and support for the former Apple PowerPC product line to follow. Any updates required to support the Apple PowerPC systems following the release for PS3 will be made available via a free download.
It's also mentioned YD 5.0 will ship with version DR17 of the Enlightenment window manager.
Hopefully we'll get additional details soon regarding what hardware features are inaccessible (which I'm assuming will be the case as it was with PS2 Linux), but it'll be nice to have an actual distribution publisher providing support this time around.
If you're interested in programming resources for the PS3, IBM, Sony, and various PS3 developers have had the following sites running most of the year:
