exactly same situation at Nikon and Canon: still no replacement for 7D and D300s.
70D closely matching D7100, both re-using the old phase AF-systems of the former top APS-C cameras.
Most important prediction: 70D sensor with 20 MP and only 1 stop "better" than 7D will be NO MATCH for Nikon D7100 sensor and IQ - not in resolution and not in DR - I expect a 1-stop difference in Nikon's favor.
Apart from sensor, 70D and D7100 are very closely matched. Body quality very similar with some metal structure on the inside and a lot of plastics everywhere else. Definitely no complete Mg-alloy shell. Viewfinder (pentaprism, 100% coverage, somewhere between 0.94x to 0.98x magnification), single SD-card slot, pop-up flash w/wireless flash commander, no AFMA.
Some advantages for Canon: 7fps vs. 6fps, fully articulated LCD, better live-view implementation w/hybrid AF (Contrast + on-sensor phase-detect), probably better video and built-in WiFi.
Definitely nothing that would justify pricing above D7100 - currently @ € 1,000 / body. :-)
