It's sad how everyone's so caught up with noise figures these days but no one bothers to measure how much detail they're getting... especially when the sensors are so different.

I agree with the part regarding the obsessive noise peepers. But don't you think that 16.2mp for a 1.5 cropped sensor is good enough with that much resolution and DR even at higher ISOs like 800 - 1600? Apart from the FF bodies, I believe having such kind of cropped sensors in the market is a good thing.
I don't know who doesn't adjust the raw data before it is saved to the card. According to my readings from Thom Hogan; Nikon and Canon has different approaches concerning the 0 values and their noise handling. Canon raises the 0 values in bit storage so that the usual bell-shaped noise values around 0 are kept (good for stacking images) but Nikon sees 0 as 0 and has no bell shaped distribution around it. This has negative impacts on astrophotography. So, sometimes cooking is a good thing... That's why I like the wording "cooking" more than "manipulating" or "adjusting"...
Kind regards,
