I've heard people in other threads talking about how they don't care about video functionality. I don't get it. How can someone love making images and completely dismiss motion pictures?
I do both and it only seems natural that if you like one you would like the other. I just can't wrap my head around it only wanting one. I can understand people having a preference, but to buy a $3000 body an never shoot video on it? Really?
In my opinion these cameras are set when it comes to photo features. They don't need to get any better than they already are. With maybe one exception, AF speed/accuracy during liveview. It's video features that are far behind where they should be and that should be the main focus right now of these camera manufacturers.
Many people who make their living with still photography don't like being forced to pay for video functionality that isn't going to benefit them financially.
For me, video doesn't boost my income.
While I agree with you're thoughts that video features can be improved, I disagree that photo features are "set". Your focus of interest will influence what you believe should be prioritized in future generation DSLR's.
