On the paper the 7D2 looks good....
I'm sure will have improved ISO performance at base ISO ( 100-400)... but how about the sharpness of the images???

Is really hard to maintain a good ISO performance AND sharpness on a 24MP APS-C sensor.

Maybe Canon has started to use the new sensor manufacturing technology.

Imho these things have nothing to do with each other, unless the manufacturer decides to hide iso noise problems with forced noise reduction resulting in a sharpness loss - other than that iso performance is just a sensor feature, and so far Canon doesn't have the edge on the competition.

Sharpness can be impaired by a strong aa filter against moire (like on the 5d3), but mostly it's dependent on the lens - and starting with 24mp many people with cheaper or older lenses will be up for a disappointment because their lens is outresolved by the sensor, for example my 17-40L wouldn't take much more than 18mp on aps-c.

What strikes me odd is if Canon makes this camera, it would mean their highest MP camera would be an APS-C format body, not full frame. That just doesn't sound logical, why would they do that? This camera would have a pixel density equal to a 61mp full frame camera, that is far beyond the resolving power of most lenses. I doubt this camera would really come anywhere close to the IQ of the 5DmkIII, that is just wishful thinking, at any ISO.
From past experiences, the a lot of people who buy a 7D aren't "pro's" etc etc.  The most of them see that it's a professional looking camera so they target it.  Then those who haven't been in the photography world for long would brag to their other friends (who don't know so much about photography as well) that their camera is "24.1 MP" which is what most consumers who are looking for a camera look for the higher megapixel.  And those who do buy are mainly Asians (not sounding racist.  I'm half-Asian) and Canon was rated as Asia's number 1 brand (well the several billboards I saw in the Philippines say so at least).  With saying that it easily attracts newcomers to buy such a camera (especially the ones willing to spend $2000 and flash it around).

I honestly hope that the 24.1mp isn't true.  I loved the 18mp all I really wish for is improved ISO performance, update the AF system, and I hope they keep the pop-up flash!

...That I'm afraid. If Canon decide to use THE SAME 10 years old technology to make the sensor, than the only way to improve the ISO performance is to use  forced noise reduction soft, and that will result in lots of sharpen loss.

Ironically, a sensor that outresolves the lens is the ideal alternative INSTEAD of having an AA filter. The AA filter simply blurs high frequencies that can't be meaningfully resolved. If the sensor always outresolves the lens, then the AA filter is moot, and you should always be able to resolve more detail, even if the lens can't match the sensor...without EVER having to worry about aliasing of any kind.

That said...

I think both of you guys are greatly underestimating the resolving power of Canon's new Mark II generation of lenses. According to my experiences renting many of them, they are unbelievably sharp...far sharper than necessary to completely resolve detail for the 18mp APS-C sensor. I wouldn't be surprised if they were good enough to resolve just enough detail for a 24mp APS-C (which, again, would be ideal from an AA filter standpoint...it wouldn't need to be all that strong), and plenty good enough for 40-50mp FF sensors.

If this spec list is even slightly right, count me in! :)
I find the current 7D to be a brilliant general-purpose camera and this just seems to make it one notch better on all fronts..
Now let's wait for the actual image samples... this should be interesting.  ;D

Now that Canon has pocketed all of the cash from 5Dii to 5Diii upgraders, they can now start releasing cameras with their revolutionary next generation sensor. Can't wait to see the discussion when DXO give it an "83".

Whether I upgrade from my current 7D to the 7D II or to Fullframe mainly depends on:
1. Sensor quality
Needs to have minimum +2 EV Hi ISO AND DR .. atv ALL ISOs, including 100. in RAW. Do not care abaout ooc jpeg
Also, I am perfectly fine with with 18MP on APS-C, do not need 24.
2. AF system
the closer to 1D-X the more likely I will take it :-) 
If it falls short on count 1 or 2. I will definitely not buy it.

At the rumoured price tag I would also expect:
* FULLY functional Auto-ISO - exactly like in Nikon D800
* Wifi, GPS built in - but not "always on"!
* Pop-Up flash with optical wireless commander - as in 7D
* additionally a built in Canon RT-radio transmitter .. that chip is probably only a few square millimeters. so fits easily alongside a pop up flash. It is not -... one or the other!
* fps .. I do not need 10 ... 8 is plenty for me, I would even accept 6 if IQ would be improved
* video .. don't ever use it, don't need it, don't want it. Buy a camcorder, canon makes nice ones.

IF I move to FF .. and Canon wants my money, it needs to be a 5D IV at the price of a Nikon D800, besting the Nikon's sensor in terms of DR.

so the 6d is 'entry level'   yet the 7d 2 is high end.
doesnt want to make me buy the 6d anymore! :(

No no no no. 7d is THE general purpose camera for MANY!!
+1 ... for 3 years 7D was my general purpose camera.
The fact that 15 pages of comments debating about the 7D II shows how popular this camera's predecessor is/was.

They could have made this a FF!!!

No... that misses the point entirely.
+1 ... if it is made into a FF, it will cost a small fortune and will be out of reach for many people like me.

Canon! you jerks! when will this company get with it and release a camera people will buy??? For years I'v wanted a camera that prints photos on small slices of cheese, so I can view my photos and hand them out as tasty snacks. Nikon has cameras that print on a huge cheese range [CR] edam in the highlights and coloured cheddar in the shadows.
Canon, you are losing me as a customer....

Grrrrr....would people quit saying entirely wrong stuff like that please?  First of all resolving power doesn't work like that.  Second, even if it did the better lenses can already resolve up into the many hundreds of megapixels on full frame.
