Canon places the 70D underneath the 7D camera, and in terms of features it kind of points to the 7D MKII if it comes out to having the same and more. Dual pixel AF technology, multitasking megapixels, image capture and focus capture at the same time is a big ask and a big call.
Anyway check the PR videos for what they say about the 70D, and pass a critical eye over the use of the new dual pixel AF technology.
