I already addressed this in my previous reply to you. Just because a camera company has developed a technology doesn't mean they should release the technology when you want, at the price you want it. There are bigger product and pricing strategies and schemes than you or I understand. The market will determine how the company responds and when they will, not necessarily one individual's Christmas wishlist. If Canon released all their new R&D tech this year in one product, they wouldn't have a product with new features the next, and then their engineers would be out on the streets begging for alms. Does that business plan sustain R&D for the future? The usual business practice is to dole out new features little by little and also slow down in response to a recession. Every big camera company does this, every big technology company does this. When competition heats up, then the doling becomes quicker, but so far, Pentax and Sony are not big competition despite what all the internet bloggers say. Haven't you heard? Mirrorless has killed the DSLR already (as of Spring of 2013, if you read Engadget, Verge, etc)!

They missed it. Not are going to miss it, but missed it.
Past tense? It's not even announced yet! Maybe you're right, maybe not. At this point, it's still a rumor.
The specs were confirmed, though. I mean...it's what the title says:
"Canon EOS 7D Mark II Specifications Confirmed"
As I replied to Don...I find it to be completely illogical to think that the 20.2mp sensor is somehow new. With these confirmed specs, I see no evidence to suggest any alternative: It's the 70D sensor. It's Canon doing the Canon thing...reusing parts. Being cheap.
Anyway..."confirmed"...means something rather specific to me.
Context - it's a "rumors" site.
Just for keeping things factual, every 18MP sensor Canon has made has had a different part number. Yes, they all perform similarly, but not the same. I would virtually guarantee that this one will have a new part number. Even if it does perform the same, that doesn't mean the off-sensor A-to-D will perform the same. In fact, it's almost certainly different just to keep up with the higher frame rate. And that might mean it performs differently. Finally what if it has some version of the Magic Lantern dual-ISO trick built in? That provides a substantial DR improvement even on the exact same sensor.
So, you're making an assumption. A series of them in fact. Those assumptions might be logical but that doesn't make them necessarily accurate. Let's wait until announcement and testing before putting such "conclusions" into the past tense.
Your free to do what you want. I also don't doubt the sensor will get a new part number. Concurrently, I don't expect there to be any significant differences, just like the 18mp sensors. I think the downstream parts, the DIGIC 6 processors, have the potential to improve high ISO noise performance. By how much I don't know. It seems to do fairly well on the PowerShots that used it, but they never had really high ISO. Sure, we'll have to wait and see on that front.
As far as any key sensor technology changes, if there are any, I suspect it's primarily DPAF. Canon did file for another patent after the 70D, which described a DPAF sensitivity improvement. Maybe the 7D II sensor gets DPAF pixels right out to the edges of the frame, and are able to still focus despite vignetting. That would improve the video features...but fundamentally, it's still the same sensor.
I'm looking for something specific. I'm looking for a major shift away from 500nm and to 180nm or smaller transistors. I'm looking for the ADC units to be moved out of the DIGIC processor and onto the sensor itself. I'm looking for the ADC's to become column-parallel (I know Canon has a patent for that, a Dual Scale CP-ADC patent). I'm looking for the employment of a couple other Canon patents that aim to reduce noise directly within the sensor hardware.
The fact that the 7D II is going to use DIGIC 6, which has been designed and still includes the ADC, tells me these things haven't happened. If they haven't happened...well, it's not the kind of sensor technology I'm looking for from Canon. I KNOW they have the technology. They have to have had the technology since the 9.5fps 120mp APS-H...they couldn't read such a large sensor out fast enough without hyperparallelism of the ADC, and their press releases even said that they moved "image processing" on-die and made it extremely parallel. Canon has the technology...they just aren't using it. They are staying the course...which is what Canon does.
So, sorry, but for me, the evidence is clear enough. Nothing has really changed.
