Thanks man, I needed a laugh. Pixel binning may not be of huge benefit to many but if you had worked with medium format digital you would understand the significance of the AA filter, and what it means to work without one.
I can see the sense in delaying and 30-35 mp would be the upper end of what I would want to see. Remember the 7d would be 45mp ish if it were full frame. Canon lenses aren't well known for being sharp in the corners anyway, for me thats not a huge issue, for some it is. I would hope people dropping nearly 10k on a camera wouldn't be using a rebel kit lens on it anyway, and L glass can mostly keep up with that kind of pixel density (the 100-400 probably stands out as one that wouldn't). I wish canon would keep the MP count under 30 though, if people need more then there is medium format which wouldn't sacrifice quality to get to 80mp.
Binning is useful in low light for sure, and in video. The big thing is the AA filter, if they do get rid of the AA filter it will make for a big change in the way we work with the files, closer to medium format. No real need for USM anymore, but careful shooting to avoid moire inducing patterns as much as possible and careful post to reduce or remove what is there.
I'm not sure on the whole waiting for a big jump thing, if they release next year that means the camera is going to be near finalized now anyway and be in the hands of folks being tested in the wild or at least very close to that stage.
