Just announced Canon iP7220 inkjet may be 6 color CLI-8 based (or not?)

On Canon's USA support website, the "Specifications" page indicates the just announced iP7220 inkjet printer uses six CLI-8 dye cartridges (Cyan, PhotoCyan, Magenta, PhotoMagenta, Yellow, and Black). http://www.usa.canon.com/cusa/consum...Specifications

The "Supplies and Accessories" page indicates it uses CLI-251 dye cartridges and PGI-250 pigment black. http://www.usa.canon.com/cusa/consum...AndAccessories

I'd be (Very Pleasantly) surprised if the iP7220 uses CLI-8 cartridges.

Anyone got specs on the CLI-251 cartridges?

• clear or opaque or partially opaque?
• capacity of Standard Size?
• capacity of XL (extra large) size?
