Usually yes. But something that is a hard value, like the AF system that already exists in other cameras, but being put into the 80D, and the features mentioned above, are all just features of a current really great AF system that the 80D gets to partake in.
I already feel the 80D making my 7D2 into an antique. Wider-than-centerpoint f/8 is interesting. Higher base ISO DR is interesting - it would allow use of HTP plus -1EC all the time, for a review image that is always dark but not too dark to check, and giving two stops of headroom. The biggest thing to get me to give up the 7D2 FPS and build in favor of the 80D would be high-ISO read noise. If it is 1/4 stop less than the 7D2; no big deal. 2/3 stop or a full stop, though, would be substantial. A stop would put the 80D in the A7s class, noisewise (without Sony RAW cooking), for focal-length-limited shooting, with more resolution to resist heavy NR. It would be the most noiseless APS-C bird camera by a good margin. I haven't heard of anyone measuring the noise though.
Almost everyone who gets their hands on pre-production cameras usually takes shots and comments on the OOC JPEGs. I would be diving right into the black-masked areas at the left of the RAW image and measuring the blackframe noise, and maybe assessing the strength of the AA filter. The 7D2's is a little too strong for shooting with TCs, IMO.
