Hello dear friends.
What do you think - Canon need this market ?
Will we see any MF cameras and lenses of course any soon ?
I'd say no.
The question you should be asking is this: what benefit would going into MF be for Canon? The market itself is tiny. It's tiny because the equipment big, hard to use and is super expensive. So say Canon went into it with the intention of undercutting the competition (cheaper, easier to use). How much would that grow the market? Enough to be worthwhile?
Now look at it from the technology viewpoint: what benefit does MF bring to the table? Does MF produce a better result in the "meat and potatoes" section of the photography business?
My opinions? No. Due to pure physics (size, weight, lens focal lengths) MF isn't very convenient in pretty much any setting other then landscapes and studio work. Outside of that MF is too big, too slow and too unwieldy. Any improvement brought to the MF game would be equally applicable to the FF and APS-C markets (aside from size, can't get around that one). Even IN the realm of landscapes and studio MF really only helps if you're going WAY big with your image. I'm not talking about a 2 page spread. I'm talking about a 30 foot tall poster. How big is the market for that kind of photography?
So, would MF bring something to the table to say a wedding photographer, or a news photographer, or a sports photographer, or a travel photographer, that would make it worthwhile? IMHO, no. The image quality benefit just isn't there for those uses, and the equipment would be bigger and heavier then FF or APS-H/C sized solutions, again for no benefit.
MF has been a niche for a long time, and the physics IMHO just prevent it from leaving that niche.
