Digital BW, The Print

I am considering a Nikon D1X. I print entirely on my Epson 7000 using 
Piezography and MIS Variable Tone Inks. Without the use of Genuine 
Fractals, has anyone with this camera printed to 16x20?  How is the 
quality of image compared to scanning 35mm, MF, or 4x5 film and then 
printing.

In RAW mode this camera approached 6 megapixels. Is this the camera, 
or is it still a waiting game for the first 10 megapixel camera?

Thanks guys,

Mike
