I was pretty skeptical when I first saw the rumors, but Canon has announced the EOS R6 Mk II just two years after the original R6.

Bryan's review with a pre-production model.

DPReview wanted more (when do they not).

Cameralabs seems to think they targeted and surpassed the Sony A74.

At least to my eye, the only "wow" update is going from 20 to 40 fps in e-shutter mode. But, that really depends on if someone really wanted a specific new feature. But, often, several modest updates do add up to something significant. Maybe that is the case here.
