nicolaiecostel: Knowing Canon, I'm surprised that they don't charge for it. Also, this could mean that they have absolutely no new sensor ready in the near future, other than the 18MP (figures..), so they cannot release a succesor to the 7D (650D to 600D, anyone) because that would mean releasing the same camera, with the changes from this firmware. They are threading water for the moment, I'm curios what will be the answer to the 24 MP sony sensor already seen in sony and nikon .
The optimist point of view on this is that Firmware 2.0 was their contingency plan for the performance changes in a 7D Mark II in case they were stuck with the same sensor again. The idea being that since they have a new sensor coming out they were able to push these changes to the current model, or at least push them out now so as to buy them more time to finish developing a new sensor.
