It seems like most of the aggravation comes from people who want a 7D equivalent either in the M mount or the R mount. Some people are agnostic about the mount (me). Others are hell bent on an RF mount. Much of this comes from people who, in my mind, think that what Canon currently offers in the M mount somehow makes it impossible for them to offer anything else.
For example, just because the current M cameras are small, they think that a 7D replacement in the M mount has to be small. I find that ridiculous. The 7D wasn't constrained by the size of Rebels, why would an M7 be constrained by previous M bodies?
Also, people act like whatever Canon has offered in M mount lenses in the past means they can't offer different lenses in the future. Again, I find that silly.
Another point of contention is pricing. People seem to think they will get an R mount 7D replacement at a significantly lower price point than either the R6 or R5. I have my doubts.
Personally, I have serious doubts that Canon will want to repeat the confusion of the past by offering APS-C bodies in the RF mount. I think they may very well be over the idea of a high end APS-C body in their full frame mount. Suggesting that really upsets some folks.
Finally, there is just a lot of uncertainty about the future path of Canon ILCs. Some folks love to stir things up with "EF is dead comments" or with "the M line is going to be killed off" comments, regardless of whether or not such comments are relevant.
There's a huge difference, which you seem to be unable to comprehend, between
hoping for an RF mount successor to the 7D Mark II because it seems to fit the needs of the vast majority of current 7D Mark II users (who often also use FF bodies and EF lenses) more than a potential M7 would and
being hellbent that Canon must offer such a camera.
There's a huge difference, which you seem to be unable to comprehend, between saying anything in the EOS M system
has to be small and saying Canon
will most likely choose to keep everything in the EOS M system small.
There's a huge difference, which you seem to be unable to comprehend, between saying Canon
can't offer anything larger in the EOS M system and saying that by all previous indications Canon
most likely won't offer anything larger in the EOS M system.
There's a huge difference, which you seem to be unable to comprehend, between being
disappointed if Canon does not offer some kind of 7D replacement in the RF mount and being
really upset if Canon does not offer some kind of high end APS-C body in the RF mount.
In other words, there's a huge difference, which you seem to be unable to comprehend, between
what you keep arguing against and
what many current 7D Mark II users are actually saying.
