While I can envision using both blacks together in some media, that does not 
address the issue of the single gray, which is puzzling for neutral-based 
output. HP's "Three Blacks" marketing term does not make it clear that this is NOT 
like the black, light black, and light light black (by whatever names) that 
Epson and Canon use. Unless the same gray ink is to be used as the basis of 
printing all grays from a very dark gray to the lightest possible gray 
(challenging, in terms of dot coverage and dot visibility) then colored inks would be 
used to fill in at the light end. So, as you note, we'll have to wait until 
outside testers have worked with the printer enough to determine actual black 
generation methods and results to get much of a picture.
