The PowerPC family is one of the most popular processor architectures around, and because of the highly portable nature of AmigaOS4.0 it will provide further hardware targets in the future. It would be eminently suitable for - and relatively trivial to port to - the STI Cell processor used in the Playstation 3, and could even be made to run on IBM's Blue Gene, the world's leading super computer architecture. How's that for scalability?
