Ink longevity is still being verified by Wilhelm Research, but it's still very close to the x400 series; could be better. The inks are completely revamped/updated to match the updated body, head and functionality. They started fresh on the Pro series with everything down to the processing core (comes with 3 instead of 1 in the x300/x400).
All models will carry a 320GB Hard Drive. Only the ipf6400 didn't have it and the 6450 did.
Not sure on sheet loading (reps didn't mention that function at the training), but we are receiving our Pro-4000 this next week and we can test everything that way.
Canon didn't necessarily cheap out on the inks. Since they added the 190ml to the options, it is a full set still of the smallest ink (just like the 8400 was the 330ml). They are still providing more ink than Epson's starter set and you will actually use ALL of the ink (without wasting money).
On the S version (8 colors), they provide 190ml for the PBK, PC, PM and G while 330ml for the MBK, C, M, Y as they use ALL 12 channels in this model, which the main colors will use 2 channels instead of one and that's the reason for the larger upfront cartridges. You're still getting more ink than an Epson LFP.
We were able to fit an 8400 through standard size doors at our office and the Pro series is just slightly smaller, but a little heavier.
We were told there is a selection in the settings to turn off the Chroma Opt since it's defaulted to print automatically on all media with sheen (make an even layer of ink across the print).
Hopefully between us and Keith, we will both have much to write about
Canon Training was very awesome on the features.
