The main target buyer for the 80D is the same as that for the previous xxD models – xxxD owners looking to upgrade. In case it's escaped your attention, there are more xxxD owners out there than all MILCs combined, so it's a pretty large target demographic. Secondarily, it's targeted to owners of older xxD models 40/50/60D).
I would have agreed with you a few years ago, but times have changed. I don't think there's as many xxxD owners as there use to be, a lot have gone mirrorless or abandoned cameras all together for smart phones.
For example, I saw more people outside Notre-dame in Paris shooting with iPads than I did with Rebels. Go to any tourist photo spot and you'll see way more selfie sticks in use than DSLRs. I was recently up on Victoria Peak above Hong Kong with my 5D3 on a tripod taking long exposures of the cityscape at dusk, and numerous young people asked if they could take a photo of the display on my 5D3 with their phone or tablet. That's photography by the masses today... it's a world where there's little to no interest in products like Rebels or the 80D.
And even those still using Rebels, who want more camera, I really can't see the 80D being that satisfying. The 6D is far more alluring for only a little bit more money. And while there are a ton of Sony haters here it seems, Sony is scooping up a lot of the discrete camera business for good reasons: outstanding image and video quality in a very compact package.
The 80D is clearly a welcome addition around here as a backup body (which makes sense given the demographics of this forum), but I can't imagine it has much appeal beyond that.
