As I understand the line up, the 7d is aimed at sports photography while the 80d is geared for video work. Both are great (and similar) cameras.
The 7D2 is certainly aimed at people shooting moving targets, which is going to include sports, wildlife, concert/event photography and photojournalism. It has the FPS, and the buffer for it. But it's also aimed at professional photographers who are more likely to use their gear heavily and in less than idea environmental conditions.
The 60D/70D/80D lineup has always been targeting high-end enthusiasts; serious photographers who care about having things like a pentaprism viewfinder, a decent FPS rate, a top LCD, etc., but who don't necessarily want to pay for or carry a heavy, bullet-proof body or need features like dual card slots that pros shooting for paying clients will insist on having. The xxD line up also has a strong emphasis on being good for video, and overall these cameras are built to be general purpose; being adequate if not ideal for many types of photography.
Canon's xxxD, xxD and xD lineups do sometimes have overlap where they meet. Technology improvements close gaps in the lineup. The 80D and 7D2 will meet on just such a boundary, just as the 60D/70D and T6i/T6s did. Sometimes newer is better, sometimes it's not no simple. To make the right choice, you really do have to dig into the details and figure out what you need and what you can live without based on what you love or long for using your current gear.
