IMHO as canon has declined and ceded a lot of market back from the glory days where they 80%+ dominated every segment, they need to go this way or really start challenging mirrorless. The problem for canon is that they have the same problem Nikon had before they turned around: protecting a market. Canon and to a lesser extent Nikon are making decisions to stop the mirrorless take over instead of embracing it. In many ways, they are the blackberries of the world facing the Android take over. evolve or die.
