In other words, Canon will soon have 3 dedicated cinema bodies in the market, but still no dedicated landscape / studio body?.. Yawn. This is just another sign that they shifting away from stills, and more towards video.
Actually, they'll have 5 dedicated cinema bodies, as they'll have the 1D-C, the C100, C300, C500, and then whatever this is.
Of course, that pales in comparison to the EOS-M/T3/T3i/T4i/60D/7D/6D/5dIII/1DX lineup they have for stills that somehow studio and landscapists have been getting by with for a while. Remember, the Canon cine line is young, so, they have a lot of niches to fill still. And, like photography, they have to cover a lot of markets that are looking for different things. The people who want the C300 are very different than those that want a C100 or C500.
