+1 about keeping the LP-E6 battery. I use them on my 5D MK3 and 7D. I would not like to give up the exchange flexibility of batteries between those 2 cameras

LP-E6? Well yes... It would certainly be handy if the 7DII batteries were LP-E6 but I'll speculate that the replacement battery will be higher capacity to drive the AF & FPS speeds higher than a couple of LP-E6 cells could accommodate. I'll happily trade the convenience factor for performance upgrades.

Well, on both cameras I use the BG. And, the performance is great (using also Lexar 16GB 1000x) I have nothing to complain

Better high ISO performance, more DR, and throw in built-in GPS and I'm good.

Nah, what I would prefer is a CF/SD combo - that gives far more flexibility - just please not an SD only like the 6D.

I hope Canon will put a good AF there.

if 5d3 isnt dual CF, why should you expect 7d2 is?

But the 7DII will not have dual Digics. Take my word for it.
It will have a single Digic 5+, same as the 5DIII and the 6D.

Here's another math that you can do:
The 1DX has two Digic 5+ processors and a 16-channel readout (official specs).
And the 5DIII has a single Digic 5+ and an 8-channel readout (again, official specs).
Therefore, it can be concluded that the Digic 5+ processor has an 8-channel readout.

Also, the 6D is capable of 20mp @4.5fps with a single Digic 5+ ... and just 4 readout channels (again, official specs).
This puts the throughput of the Digic 5+ processor at 20*4.5/4 = 22.5 MP/s per channel.
That's a throughput of 180 MP/s total for all 8 channels on the Digic 5+ processor.

Realistically, Canon will not go over 10fps in 7DII and will not put dual Digics in it.
So, I'd say that the 7DII will be spec'd anywhere between 16mp @10fs and 22mp @8fps ... with a single Digic 5+.

I'd prefer if Canon puts 16mp/10fps in the 7DII but it's more likely that they will go for 20mp/8fps.

One thing is certain, though: the dual Digic V spec is fake and this whole 7DII rumor is a lame [CR0] rumor.
Could you please provide reference that 6D has a different DIGIC 5+ processor (with 4 crippled A/D channels), than those of the 5D3 and 1D X?

All my references says it's the same DIGIC 5+ with the same 8-channel A/D, which also explains why the same DIGIC 5+ designation (e.g. not DIGIC 5-)

Assuming conservatively that 7D II is to remain at 18MP @8fps, that's ~144MPs, which is still higher than the existing 5D3's single DIGIC 5+ rating of ~134MPs. It's hard to guess how much headroom is left with a single DIGIC 5+, but I wouldn't bet on it. IMHO, it is highly probable, although not a certainty, that dual DIGIC 5+ is a real possibility for the next 7D.

interesting. the channel info is stated on the bh store page(http://www.bhphotovideo.com/c/product/892349-REG/Canon_8035b002_EOS_6D_Digital_Camera.html) so that sounds about right. single digic for the 7d2 and just a made up rumour.

from the B&H link:
"the DIGIC 5+ processor also delivers overall speed and power to the 6D and utilizes dual 4-channel A/D converter"

Looks like the same 8-channel setup to me. At the minimum, I'm betting on dual DIGIC 5 (non '+').

Isnt't the difference between 5 and 5+ just the frequency at which it's clocked? In that case they could easily clock it at some inbetween frequency, or if they managed to improve a bit even higher than in the 1DX, after all, that's what all other processor manufacturers do.

+1 for better DR and improved ISO performance. I guess it will come down to how improved the read noise is going to be...

Also, I would appreciate if it did not make the 100-400 look bad. Just ordered one  ;D

Cheers!

I am not sure if that goes with the current level of weathersealing that 7D has. I assume the successor of the 7D will not be less weathersealed.
