Sweet.  Time to start saving those pennies, just in case. About 1.2 million of them ought to do the trick.

Why does everyone think that the 75MP quoted implies that it's dual-pixel, and that number is twice what the actual filesize will be?  Canon annouced the 70D as 20MP, and it has 20MP file outputs.  I'm not sure why everyone keeps jumping to conclusions on it.  Just because it sounds like a really big number?  Because it would have a pixel density almost identical to the 10MP Nikon 1 series cameras (J1, V1, J2, S1) or be equivalent to a 28MP Canon APS-C camera?

The term megapixel has become rather conflated with what should probably be termed megasensel, something that we can thank Sigma for in their marketing of their Foveon sensors. If prior rumors posted on CR are indeed true, it is more than likely that the 75mp FF camera is actually a 25 megapixel (in terms of output pixels) camera with 75 million photosites (million sensing elements, or megasensels), 25 million each of red, green, and blue photodiodes, one of each stacked vertically at each pixel location.

Theoretically, such a camera would have lower luminance resolution than a bayer, but similar or higher color resolution as a bayer. If Canon solves the problem of poor red performance deep in the silicon, such a sensor should have rather phenomenal color fidelity, minimal color moire and low luminance moire.

If the sensor is indeed a 75 megapixel bayer design, I totally agree...it will be a camera with 75 literal pixels. If it makes use of Canon's new dual pixel AF approach, then that would mean the total number of photodiodes would be 150 million. I guess I find the use of dual pixels unlikely unless Canon has indeed moved to a smaller fabrication process.

A few wild guesses:

First, it's mirrorless with an EVF good enough for professionals;

Second, it has 80MP, but they're paired as in the 70D;

Third, when they say "high frame rate", they mean 24 to 30FPS;

Fourth, it's in the 1Dx body 'cause it's a power hog.

With that 75 megapixel camera, burst mode, and a good lens you probably could get a picture of that swallow carrying a coconut... and with enough detail to determine the type of swallow and if you compare movement to a background, determine the airspeed.

However aside from DualPixel and VIDEO improvments I still am waiting for a better than average ISO & DR.

Pull a magic lantern and read those dual pixels at two sensitivities. ;)

Will Canon releases more NEW lenses to support 75+ MP?

Nope, they leave that to Sigma  :P.

75MP + high frame rate might lead to the conclusion that this camera uses a "three subsensors per final pixel" design - as others mentioned here:

Using 3 x 25 sensels for R, G and B avoids the calculation of the final image from the Bayer patterned raw data. I don't know how much processing power is needed for Bayer sensors but if you want to to it right it might be a lot.
Using clean RGB-data for photos or video means just storing numbers.
Reading out three layers of a sensor independently eases the readout process and AD conversion by simple parallelization ...

This is all exciting, but for all the complaining that you see about DR, not enough pixels or some other little thing, it's miniscule from the real-world oohs and ahhs that you get from well composed 1D & 5D (current AND previous gen) bodies . . .

Just because they can get BETTER doesn't mean they're not great already.

What are the odds that this mule is actually a Frankenstein creation, designed to test multiple new components?  E.G. throw this new sensor in which may not make it to market right away because it's not perfect or financially feasible to push the limits of a new or experimental processor?

Sweet.  Time to start saving those pennies, just in case. About 1.2 million of them ought to do the trick.
Up here in Canada, the penny has been phased out.... I can't save up 1,200,000 of them so I guess I can't get this new camera. Pity, a 75 Megapixel camera would have been great for taking facebook photos.....

They phased out the penny?

I haven't lived up that ways for about 12 years.  When I was a kid, we had 3 stations, and they were all Canadian.  Amazing how much of the news was all US news, unless there was an election, or, you know, Quebec (we can still use that as a verb, right?) ;D

Not sure that de-bayering takes all that much CPU with a good algorithm. Canon might even to part of it in hardware, since they tend to use specialized hardware circuits for various things which ease the CPU part. But for writing out raw files, they don't really even need to do that. Leaving aside the embedded thumbnail jpg that's usually included.
