Why the 7D2 over the 80D? Moving from the 50D, the 80D would be the more logical choice, and it is a little better in low light than the 7D2.

Im not so sure - the user interface of the 7D II is much more similar to the EOS 50D - the OP won't need to re-adjust - a particular advantage if he plans to keep your 50D as second camera.

Focus area selection is more convenient with the 7D II as it has the dedicated button (as the 50D) - I use it all the time on my 7D, 40D and 20D.

If the OP plan to sell the 50D, the first point does not matter that much - he will re-adapt quickly.

The 7D2 is optimized for sports (high speed shooting) and wildlife (complex focusing options for rapidly moving subjects) - but the 80D is MUCH better than your 50D on those aspects anyway.

In both cases, you can expect about a 1 to 1.5 stop improvement in high ISO, where shooting at ISO 3200 on the 80D or 7D2 would be about the same as ISO 1600 on the 50D - and with the right camera set up, maybe you could even go to ISO 6400 and still be OK with the noise level.

Note that a key for low noise is to avoid boosting the shadows in post processing, which means the correct exposure is key. Too often people under expose in low light and boost the shadows in post processing, greatly increasing the image noise (the noise of an ISO 3200 image boosted 1 stop in post processing can be higher than that of a correctly exposed ISO 6400 image).
