More pixels are coming
A suggestion that a high megapixel camera is coming from Canon, and could be introduced near the end of 2012. Alongside the camera would come new ultra wide angle lens(es). It was suggested both a zoom and a prime in the area of 16mm.
I warn that this sort of conjecture will be a regular occurrence going forward I think. There is a large number of people in the community that desire a 35+ megapixel camera from Canon.
Some have suggested the upcoming 4K DSLR will be the high megapixel camera. I don't believe that to be true, as the high megapixel count is definitely a request of the photographic community, and paying for high end video features is probably not something that would make the segment too happy.
