The sensor is an analogue device so it can't be 12 bit. The ADCs  
produce 16 bit info, but Nikon's RAW compression isn't as good as  
Canon's so they chop off 4 bits of data that they say you can't see  
(kind of like how minidiscs did with sound) in order to get the file  
size smaller.

Some of you should join the photogeeks mailing list btw. That would  
be an ideal place for this question.
