...As someone else said, different strokes for different folks.
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.
I agree with Neuro - there are many better video systems out there than my 7D. Its nice to catch a few seconds of action when I'm already set up but to go out with it mainly for video - not so much.
And I very rarely use live view. Increased AF speed during liveview would be very low on my list of improvements I need. I'm still hoping for an APS-C (or better yet, a full frame with the same pixel density) with better high iso performance.
