Some others closer to the chip industry may be more accurate and
better at explaining this, but I believe that chip manufacturers
(AMD, etc.) do allow (certain) customers to come to them with a
design which in turn they manufacture. In theory, this cuts down
on R&D costs, etc. and keeps up the flow of work for the
fabrication plants.
Then there is the politics of business. Who is Nikon aligned with?
Is it Sony?
The tough thing for Nikon is their relative size to Canon. Size
equals dollars for R&D. At the same time, sometimes size can hurt
a particular product line development in a multiple-product
company. If photography is not "pulling its weight" in a large
corporation such as Canon, then it doesn't get the attention more
successful (and profitable) divisions do.
I wonder if at some point the DSLR cameras will have the ability to
swap-out CCDs...making upgrades less expensive. I believe the
professional video camera world has that....Sony pro-vid-cams can
swap upgrade with new chips without having the whole body etc.
Cheers,

Now that Nikon is making its own sensor, it seems on the surface
that the market of DSLRs has changed. Has it? Peronally, I think it
doesn't change a thing because until now, Sony has been making the
sensors to Nikon's spefication any way.
