seems the 7d2 may still have some ugly noise structure, if not the heavy banding of its predecessor, based on some of the shots in the review here and elsewhere.www.canonrumors.com/wp-content/uploads/2014/11/7DII-ISO-800-6400.jpg
but that kind of noise is still workable
Not at all surprised that dxo-measured DR has barely improved at base and low iso.
However, the AF system, weather-sealing and speed still appeal to me, so I'll be getting one.
I missed the performance aspect of my old 7d, even if I despised the stripey low ISO performance. The 7d2 gives me a bunch of useful upgrades, misses a few it should have had, and the sensor is... possible Canon's best crop sensor yet, if not nearly as good as the competitors.'
All that will, to me, provide a body that is "good enough" for some of the long lens wildlife type shots I'll use it for or some fast paced action shooting. if I didn't still have a decent stock of Canon EF/s glass I would not bother with it.
If I find it still underwhelms, out it goes, and the rest of the $L lenses with it. This thing will be my make-or-break decision on maintaining higher end Canon crop gear. I can see MFT bodies coming up another notch or 2 in the next 2 years, possibly enough to challenge even sports-shooting DSLRs for capability as they're already close to par for IQ.
