Hi,

Any plans to realse in Cran binaries for R base & packages, for Windows
using 64bit, now that the AMD 64 is coming out?

No plans, AFAIK.
Are you volunteering to compile R base (there may be need for some adjustments in the code, as well as in the Makefiles) for CRAN?
The maintainer would need both, an AMD 64 machine, and a 64-bit Windows in order to compile.
I'm volunteering to make the packages, if you'll buy an AMD 64 machine + 64-bit Windows for my office. ;-)



It seems a perfect match for cost effective high performane number
crunching??

I don't know whether it will be much faster to use the 64bit mode, because the internal structure of x86 processors for number crunching already has been 80 bit for floating point arithmetics. Additionally, you will need more RAM for the same problems which slows down some calculations.
In principle, you can extend the 2GB limit of the R process, though.
