I think an N version has a lot to offer - it'd include all the mkIII improvements and add full frame, huge resolution (22mp is the figure usually bounced around here), stupidly huge buffer...
Plus the N version is due an upgrade in the menu department, plus having all the new custom functions the mk3 has added to it...
The mkiii isnt high enough resolution for a lot of applications the N is used for, so there's still a need for a mk3 N...
