I have a story interesting somehow.

One of friends is a nice guy who is a technologically knowledgeful
sales director and once was involved with MIPS Japan operation.
(People would be just astonished at how large Japanese companys
contribute MIPS sales in whole these days)

He sez; When R4000 was under development, there were technological
arguments about how to achieve higher performance.  The arguments were
done around, in short, to take R4000/R4400 way or R4600 way.  The
former was taken.  Then, the latter design was revamped when QED group
was established.  The evolutionary path of MIPS processors followed
along R4600/R4700, R4300, R5000, RM5200 and so-on.  Now, I'm a bit
suspicious of that R10000/R12000 would run into an evolutionary
deadend before successful.
