I'm not going to get overly excited about CR1 specs from an "unknown source."
Reserve judgment on a sensor until real specs and results are known (probably won't know that until several months after the announcement). Consensus on this forum seems to be that noise and dynamic range improvements are more important than the number of pixels. Absent a major change/breakthrough in sensor design, I would be surprised if Canon ups the pixel count of the APS-C sensor above that of its full frame offerings.
New battery is a mild disappointment, but I assume Canon would make the change because they have to for design/engineering reasons.
Please, let them keep at least one CF card slot in a dual card system.
New ergonomic design is too vague to warrant comment at this point.
All in all, I'm more excited that we are finally getting rumors about a 7DII. At this point, the content of those rumors aren't as important as the fact that there are rumors circulating.
