...are you ready to accept the additional costs of flash memory storage, temporary image storage, and archiving of the larger images to keep your 14 Mpixel camera happy? Keep in mind your basic vanilla 512 Mbyte flash card (now about $200 each, sometimes a little cheaper on special) will hold something like 73 JPEGs but only about 36 (at most) RAW files. Compare that to a D100, where the same card will hold about 170 JPEGs and about 73 RAW files. If you buy a 14 Mpixel camera, you better be ready to lay out for some expen$ive 1 Gbyte flash cards to do any real shoots, or trust your soul to fragile microdrives (that aren't that cheap, either).
If the D100 does the job for you (prints up to 11x16 at high quality) do you really need a 14 Megapixel camera? At some point it's like hunting gnats with an elephant gun. One could argue that a 6 Mpixel full-frame camera might be in some ways superior to a 14 Mpixel full-frame camera. (Think higher ISO, lower noise.)
