Where the heck is the 70D or 7D mkII?

[dlleno]

getting back to the original topic:  I suspect one reason we haven't heard more about the 7D2 is that Canon is trying to protect holiday sales, and may announce something soon into 2013.  They've telegraphed the big MP FF (to keep people from jumping to Nikon I suppose) but they have not telegraphed anything re:  the 7D2

They've telegraphed the big MP FF (to keep people from jumping to Nikon I suppose) ...

Canon hasn't telegraphed anything.

The 46mp figure is derived by scaling the resolution of the 7D/60D sensor to FF:

• 18mp * 1.6 * 1.6 = 46.08mp

Not sure who thought that this was a good idea but it looks like wishful thinking to me.

40mp would be much more palatable, for example.
A 40mp sensor will be able to achieve UHD video resolution (3840 × 2160) with 2x2 pixel binning.
Canon is already doing 2x2 pixel binning on the 5DIII for HD video (hence the magic number 22mp).
And it would only make sense if they do the exact same thing on a high-MP camera.
This would require a 40mp sensor, though, not a 46mp sensor.
So, 40mp is actually more likely than 46mp for the high-MP camera.

The 46mp figure is not only not telegraphed by Canon but it's also a very weak [CR0] rumor.
