Nikon, like other companies, is a business and wants your money. One easy
way to do that is put in more pixels, which requires a very small development
cost.
even if it's a 'very small development cost,' the camera's image
processing engine needs to handle all the extra pixels, so there's a
development cost there too. otherwise it will be pig slow and nobody
will buy it.

But, but, but look the pixels are even smaller. Well, so much for the people
that say the 4/3 system is crap because the pixels are to small. Nikon and
others will continue make them smaller. Now just wait for the 2X increase
in time to store the picture. Let's count. A fast Compact Flash is about
10-12MB a second. We have a 24.4MP, which is a lot more than 24.4MB, so
we have about 2.5 seconds per picture.
actually, the fastest compact flash cards are about 40mb/sec, plus the
raw file can be compressed. furthermore, the camera can buffer several
images. write time isn't a huge issue.

Just FYI, I am using the Sandisk Extreme III SDHC card, 4 gigabytes
20MB/second=133x
on my Nikon D80, and I can say from my experience, that the slow
feature is only waiting for the flash unit to recharge ;-) after
taking a series of indoor photos. It isn't the SD card's problem, as
I can see the green light (writing to media) on the back of the camera
go out LONG before the autoflash READY icon reappears in the
viewfinder.

Now if you have a D3 and are doing fast sequence shots, _maybe_ you
need faster than 20 megabytes/second write time, but I'm not certain
about that. My limitation is the time it takes for the strobe light
to recharge. Just a note.

Compact Flash is different, but this camera doesn't use Compact Flash.
I don't know if that is a good thing or a bad thing.

Nikon is making lots of new lens for the current CCD size. Thus they
will not work on a full 35mm format CCD. But, soon, very soon Nikon
will be forced to a larger CCD format. Then all your new Nikon lens will be worth
crap... Canon is doing the same.
except the nikon dx lenses fit on a full frame body and the camera
switches to dx mode (which can be overriden if desired). canon ef-s
lenses physically cannot mount on a full frame canon camera.

also, there's still millions of dx cameras out there and good lenses
hold their value.


Just because the disk is or may be fast does not mean the CPU can provide
data at that rate. The D80 may get 10MB or so, but that is only a guess.
