Well at least they finally did it.
Do you know if the pivot bolt at the dropout is different than previous years? That would make a retrofit much more difficult and not worth the effort.
It will improve the working life of the suspension significantly. Someone has already inquired about getting a full bearing replacement set for this frame. They gave me the part number on the side of the beaing for the dropout. It is not something I could find right away, so I'm letting my California supplier hunt it down. Hopefully it's not a custom bearing, and I will be abel to get a supply of them. It will much less expensive than the bushing/sleeve units on the pre-2004 frames.
If I am able to get some, I will look into a retrofit for the older frames. Hopefully I can work something out that doesn't require any machining of the frame.
