Many of us on this forum have been asking Canon to catch up with Sony, but we want Canon to catch up with their sensors, and NOT the horrible evf!
Unfortunately, the EVF end is inevitable. See here:
"... it’s inevitable that DSLRs eventually become mirrorless... DSLRs are too complex to continue to drop in inflation-adjusted pricing and stay in that under-US$1000 pocket. So we’ll see separate parts (meter, focus sensor) move into the ever-improving image sensor, and the things they previously needed to support them disappear. Exactly the way Sony has done it in the A7 series...
Mirrorless approaches will drive out problematic complexity and cost; they remove components (meter, focus system) and put them on the sensor itself at no other tangible cost than R&D."
That's silly. Pros don't give a flying you-know-what about whether they're in the under-$1000 pocket. They care about things like low latency, maintaining dark adaptation of their eyes at night, fast focusing speed, and ability to see critical focus with the naked eye (at normal f-stops, anyway). EVFs can't deliver that combination, nor are they likely to be able to deliver it within the next ten years.
The OLED displays are getting close to not blowing out your night vision, but they only last two or three years, and they have poor resolution, which means you can't focus accurately by eye alone (without zooming in and losing the ability to pay attention to what's happening around you, anyway). And LCD-based EVFs have higher resolution and longer life, but have crap contrast and can't get very dark. And latency and focusing speed have a long way to go.
I just don't see EVFs replacing OVFs for high-end still photography gear any time soon. It's not that they're not quite ready; it's that they're nowhere near ready. In theory, I could see them take over the Rebel line, but in practice, I can't see that, either. the problem is, they won't be able to call them DSLRs anymore, and a sizable percentage of the folks who buy low-end DSLRs buy them because they're DSLRs. Half of them don't even know what DSLR means, but they know that they want one. So I would expect mirrorless cameras to continue to exist alongside true DSLRs for many more years even at the low end. Then again, what do I know?
While I agree entirely, and have suffered from using the C100's awful EVF during daylight enough to prove it, I find the Rebel line's finders so poor that I would take a great EVF over their dreadful OVFs in some circumstances and I think most inexperienced photographers who want WYSIWYG exposure, histograms, etc. would agree. Sony has marketed faux-dSLRs for years to the gullible; as have others. If Canon does, no huge surprise.
The idea that an EVF is better is laughable. Even the most precisely calibrated monitor won't retain the color gamut, resolution, and contrast of real light. If you find yourself preferring EVFs, either learn to shoot or consult your eye doctor.
But I've been spoiled a bit. The 5D Mark III has a gorgeous finder. I've used film cameras with poor finders and I realize it's all relative. I've found the Alexa to have an adequate EVF, but a mercifully uncluttered one (not even the option to pull up a waveform monitor or histogram!).
