Agree completely, I am looking to mirrorless for something to finally replace my Rebel with super wide lens that, I carry everyday for walks with my dog. My God, just give me high quality mirrorless with some kind of lens in the 14-16mm FF range, I don't care for the price, and of course I will still keep all of my other SLR bodies.
On the other hand when mirrorless technology obviously will get really advanced, exceeding ability of the SLR, it may become financially sound not to support both systems and mirrorless will also be build in the form similar to the current SLR to preserve ergonomics, weight, ability to mount large lenses etc.
In any case SLRs probably will be replaced at some point if not by so called mirrorless than by some kind of other technology that will be cheaper, more efficient and better.
There is no reason to cry... just roll with the punches learn, and take best shots you can with available technology.
If changes like that will kill one or two companies (hopefully not Canon) it only will show that there was something wrong with the management, and usual suspects are lack of imagination and arrogance.
I think people are mixing up capabilities and form factors. Mirrorless camera's will most certainly one day match the capabilities of DSLRs. But I want a big sturdy camera for my shooting.
It's all about what a camera is good for. And people are just assuming that because a mirrorless is as good as whatever other camera then people will use it. But I don't take my desktop to a coffee shop and I don't edit photos on my laptop at home. Even though they are close to the same speed each has it's proper uses.
I think it's time we got over this confusion about the two. I actually like hauling my gripped 7D around with a 70-200mm and a flash. And I wouldn't prefer a lighter version of the rig. One of the main reasons I upgrade from my Rebel was that it was too small.
But, maybe I'm just a weird person. All my favorite TV shows get cancelled too...
