I'm curious about it as well, but I'd be VERY wary of the permanence of any fluorescent pigments... In general they tend to fade extremely quickly, unless Canon has figured out something really special. Also, don't expect the robustness and ease of use of the 8xxx series, these new machines can be a lot more fiddly. I ran a 4000 and a 6000 for years, and they constantly needed feed adjustments to get rid of banding caused by the paper not advancing at reliable intervals.
