Interesting commentary from Thom Hogan: Big Updates versus Small Updates
 
overall i agree with Thom’s comments, people forget how far things have evolved.

i do think he is wrong about the expeed8 tho. i do think we’ll see an expeed8 instead of a “helper chip”. but i don’t expect it to be a whole new thing, i expect it mostly to be a faster with some new features.

generally speaking it’s easier to simply drop in a better chip than accommodate something DIFFERENT

The dilemma might be that an Expeed 8 won't be ready within the next year or so, therefore the "helper chip" approach as used in the Z6II/Z7II. Just a guess, though.
 
as an aside, and it's deep speculation, but i think the dual expeed6 design was something they planned to do more with, but abandoned in favor of the expeed7 centric overhaul.

it really didn't make sense to redesign the logic board (and all the other changes that would also have to happen) to house that second expeed6 for the very modest features we got because of it.

it makes more sense to me that they had a change of plans and it simply didn't make sense to put more r&d into a (then) dead approach.

just a guess

it is a good point that it really depends on what they plan to tackle with it.

we can assume they will need a major revision to handle any significantly new tech, like, let's imagine, say, a 50mp global shutter camera, or some sort of new red influenced new shutter tech.

but i'm guessing we're a generation out from that. so i'd expect them to have a major expeed/architectural update timed to coorispond to that.

so in the mean time, you either try to stretch the expeed7, or you do a minor spec bump. i expect the latter because i don't think you can handle things like cfe-b v4 with the expeed7 (i don't know this for sure, it's a guess, but generally speaking, it makes more sense to do integrated packaging, so i'm guessing they need a new chip). so handle faster i/o and maybe faster processing to handle c2pa directly in the pipeline at speed including faster speed. ie, the whole pipeline, including the new c2pa part, needs to work at speed for like 30fps.

Clarification on 50mp global shutter.

There isn't one available for non-defense purposes. The Red Raptor 8k has a 35mp one, the largest on the market, probably costs $12,000 or so, and it doesn't fit a full-frame body. Being VistaVision, the sensor is longer by 4mm (but shorter diagnol). Also, it's designed by someone else (probably Forza Sillicon) and made by Onsemi. Finally, it requires active cooling. Not clear what rights if any were transferred to Nikon when they bought Red.

The first global shutter in a Nikon will almost certainly come from Sony, but only after they put it in their own flagship and it won't be bigger than 24 or maybe 26mp. Fast readout rolling shutter is most likely what will dominate high MP cameras for a long time.
 
fair. i didn’t really mean that as a prediction in itself, but just an example to help people imagine changes that might require a significant update to the expeed architecture
I agree. And Nikon doesn't make radical changes lightly. My work doesn't require the performance people are looking for on the Z9ii, and I think incremental improvement will satisfy most users.

I think you’re correct regarding global shutter sensor size. And I’m darn near certain Nikon won’t be on the bleeding edge. The financial resources required and the subsequent risk is not in alignment with its business strategies.
 
Cfexpress 4.0 would require significant hardware and software rework and I can’t see that appearing until a new chipset, the current performance of the Z9 doesn’t fully utilise the current cfexpress 3.0 bandwidth.
my theory is the expeed7 only has one pci lane to the cfe-b (like a raspberry pi) and _that_ is the limitation, not the actual ability of the processor to fill the bandwidth pipe.

in fact, i'd be surprised if this didn't look a lot like a custom raspberry pi.

so my theory is they need a version that has more/faster pci lanes.

if my web of speculations hold together (doubtful, lol), then they wouldn't really need a lot of sw work that would be taken care of with the hw and driver layers.

basically, it would be similar to moving from a pi4 to a pi5
