>>> Chung, if SUNW really believed in the Java model, they would be coming out with dual-instruction-set machines that they would use in their entire line.
I do not think that a transition to Java-based hardware is possible without a dual instruction set, as there is too much legacy software that is going to be around for many years to come. Without a dual instruction set, the risk is too great to switch to Java-only processors, and only organizations that can afford to maintain a mix of Java and non-Java processors will be able to transition. This leaves most companies out.
As long as Sun positions Java as a specialy niche, it will be that. When Sun and Intel come out with dual-instruction-set machines, we will know that the Java age is truly dawning, and an orderly and rational transition can take place.
Until then, it is all noise. When Sun has the guts to put Java hardware in it's entire product line, we will be there. They haven't done it, and I don't expect it for some time. But if the transition occurs, I strongly believe that this is the way it will be done.

Jon:
The SPARC architecture will not go way. It will remain the heart of SUN's server product. The future sparc processors will have architectural features that will enable Java byecodes to run very fast.
Java chip are designed to be simple high performance processor that goes into client devices ... like PDAs, mobile phones, network computers, or more powerful multimedia client workstations. The key to Java chips is that the simplicity in the architecture (even simpler than RISC) allow it to be a low cost, solution for business and home market.
The Dual instruction set strategy will delay processor development time and will increase cost exponentially. A better way to maintain legacy is to simply include Java chip as a add on co-processor. When the Java chip comes out, there will be a add on PCI card that you can buy for about $100 WinTel PCs that will allow you to run Java applications much faster at very low cost. I think this will happen sometimes next year.
