Digital BW, The Print

I saw the posts on here earlier mentioning the Lyson/Bowhaus team up 
re a new set of lyson black and white inks - also this report on the 
PDIA website
http://www.pdia.org/news/05_10_04news.asp

Does anyone have any further info on this? Nothing on the Lyson 
website so am wondering how new these inks are and whether we can 
hope for/expect reduced metamrerism compared with the quad blacks & 
small gamuts
