I understand that AmigaFive project had been canceled. It was very ambitious, very expensive (would have very quickly gone WAY beyond the initial $6000 evaluation board purchase) and Momentum probably wanted more of the work to be done by the project members, rather than serve as a contract design house. The project lead claimed he was to refund all donations to the cause he had received.
If you google around searching for 8641 information, there was one web site I saw with discussion forum where someone hinted that the Pegasos3 may use that chip instead of the G5. I'd take that with a big grain of salt, as it wasn't anything to resemble an announcement or anything official, just some guy mentioning a rumor. As for when the Peg3 might be available in either configuration, who knows...
Everythign I've been able to learn abot the Atricia-I came from a Mai Logic press release from a couple years ago. And that ain't very much. When it is released, I'd imagine Eyetech will license Mai's reference design, perhaps make some alterations here and there, and rebrand it as the G5 AmigaOne.
