It is mostly a camcorders. Why it can't be a DSLR?
The new rumor mentioned about EOS 70D, with 3" flip screen (some people take it as 3.0fps as a mistake), if there's on chip phase detection AF, with the flip screen, it will be better for shot over head. It is what 650D/T4i has did now, but it is a little of low end, and not strong enough.
It is also said that the sensor is the same between 7D2 and 70D. Maybe it's idea of:
7D2 prefers the users of extreme, who are mostly using OVFs. Just thinking of 6D, 5D3 or higher. Some people hoped 6D should have a flip screen, as 60D.
70D prefers the users of mainstream, who uses screen more often, and with the help of flip screen, LV or video is more easier. It would take a position of video DLSR for APS-C format. 1D C is alternative 1D X in FF, there should be an alternative version video DLSR in APS-C.
