seems like a step backwards.
but i'll be using this camera at ISO200 and below, i just want
the extra megapixels.
then again he said the firmware pushes it back down to 12.
"Do you
really want to pay a $3,800 premium over the D3 for a mere 42%
improvement in linear resolution? Why not buy a D3 for speed and
low light, and buy a Canon 5D Mark II for high-resolution
full-frame shots for $2,700, and pocket the leftover $1,100 to go
party? Very, very few photographers know what they're doing well
enough to get this sort of sharpness at the sensor, so for most
guys, D3X images will look the same (or worse) than D3
images."
ok so its either a D3Xs, D4... or i just get bloody batter grip
for my D300 because i prefer using a battery grip for portrait
shots 
Get the D3 lah - FX is better than DX for portraits.
As a Canon shooter, if was going to get serious about portrait
shooting, I'd be getting the 5D or 5D2 instead of trying to get an
APS-C body to try and do the job.
