I'm still bummed that Canon has STILL not demonstrated they are getting competitive again on the sensor front...re-purposing the 70D sensor in the 7D II just smells really sloppy and cheap....
The 70D sensor is competitive. So what would you like them to do?
Resolution? Better be north of 40 MP to see a real difference, and that's only for those of us who regularly make large prints of finely detailed subject matter (i.e. landscapes shot from a tripod at optimum apertures). Not even Sony can pull that off in APS-C right now and retain high ISO/DR.
Total DR? The 70D is 1/3 stop behind Exmor.
Shadow latitude (noise)? You yourself showed how ridiculously small the difference is when NR is intelligently applied. When I first saw a Canon v Exmor pushed shadow test I thought the tester was purposely lying because I had never seen noise that bad...because I never turn off default NR when pushing shadows hard. In fact I apply more! I routinely push shadows 2-3 stops even with the old, noisy, 7D sensor. The thing I run into pushing shadows is not noise, but a tonality/fine detail/microcontrast wall, and you hit the same wall on Sony.
High ISO? In the DPReview and IR studio comparisons the 70D looks pretty much the same as the D7100 (for example). I would shoot either to 6400 if need be.
Color? Canon seems to have nailed that one. Other people complain and profile their sensors to try and match Canon color.
The next major jumps are going to involve 16-bit designs, multilayer sensors, or some other technology twist. We are well into diminishing returns given the state of sensor fabrication right now.
The only thing "wrong" with Canon's sensors is they score poorly over at DxO relative to Exmor. So do Hasselblad medium format sensors! Only Hasselblad fans are sophisticated enough to know DxO is a joke. I doubt any of their users are silly enough to jump on a forum and say "If Hasselblad doesn't do something about these sensors I'm buying a D810!"
I hope Canon makes a major jump in the 7D2 sensor by applying NR in camera even to RAWs and therefore gaming DxO to get a higher score
