Digital BW, The Print

I was reading a forum on the R2400. Someone was speculating that with 
the new imporved B&W available on that printer, that third party inks 
would soon become obsolete. My knee jerk reaction was that this is a 
real possibility. Then I thought further. Even if Epson optomizes the 
system to make really great prints on their paper, I don't see them 
ever fine tuning it to all the different fine art papers out there, 
and since there will more than likely always be a demand for the 
ability to use a variety of papers, we will prbably need the third 
party inks to go with them.
