Just a thought ... "Canon releases (affordable) Medium Format camera". Wouldn't that be something?

Even if the camera would be affordable, the lenses wouldn't.

* I think a square 36x36mm sensor is much more likely than a medium format one; because it allows you to keep using your current canon glass

* vintage medium format glass is cheap, and usually good too (e.g. carl zeiss jena for pentacon six)

MF market is not that big as of DSLRs, changing the system from one brand to another is always expensive. So if new MF camera are released in future around 8-10K range, and glass extra. yeah pentax came with 645D, i don't think canon will soon be planning to design new MF Camera, but sony is likely to do first .

I would love a 36x36 sensor in a Canon camera. I think my picture in my style would benefit from this

Really?  Is this the new math?  Have the basic principles of geometry changed when I wasn't looking? 

The largest square that can be inscribed inside the image circle of an EF lens (43.2mm diameter) is a 30.6mm square, not 36mm.  So, if you then pull a 3:2 rectangle out of a 30.6mm square sensor (30.6 x 20.4 mm), you get a resulting image that only slightly larger than APS-H. 

Alternatively, they could put in a 36mm square sensor and you'd just waste most of the corners...so, would you pay $12K for a camera with the build quality of a 5DII (cost increase based on the number of 36mm square sensors that could be pulled from a silicon wafer, compared to FF sensors)?

EOS 1D X, EOS M, and lots of lenses

neuroanatomist is right again.
My suggestion would be: make a 36x30mm sensor. Use 36x24 for 3:2 images and 30x30 for 1:1 images. So much win!!!

I'll share with you my imaginary sensor. It is very efficient. Only 3.3% of its surface is never used. Canon, this one is free of charge.

It's not like you invented it or something :). Panasonic did it in their LX P&S for years. I don't think they would make a larger much more expensive sensor and waste those precious 3.3%.
FF + primes !

As a sensor gets larger, the cost increase is not linear.  Right now, a FF sensor is very expensive to make, a 36 X 36 might cost 10 - 20X the price.  The number of pixels on it are not the factor, its the area.

Then, the lenses will start at $3500 and go up, - way up.

Heres a somple 35-90mm f/4.5-5.6 MF zoom, imagine the price of  a f/2.8.
