To create the same brightness level, more amplification to the signal is required which creates more noise.
That's an over generalization. You want to tell me that Canon's 5 year old 12MP FF (1Ds) has way less noise then their more current 17MP 1Ds mkII? Canon has been pushing pixel densities while still retaining the same S/N performance of having larger pixels. Sensors are effectively improving in sensitivity on the pixel level. Dynamic range of the digital camera hasn't really changed much because camera makers have been focusing on shrinking pixels for now. However, I do hope that Canon stops at 21 MP and then focuses on increasing overall dynamic range instead. They'll then whip Nikon's butt if they can get a camera that actually takes 16 stops worth of data (not the 11 that most all dSLRs take).
The only spec that concerns me about these new Nikons are the real ISO: 200-3200.....boosts to 25600
Common, we know that given Nikon's ISO record, 25600 is going to be unusable (lets just hope that they can produce good ISO 1600 and 3200). Instead of focusing on such high ISOs, I don't understand why Nikon doesn't have a native ISO 100......I use ISO 100 way more times then ISO 1600. It's also an indicator to me that their dynamic range is limited (100 would be the absolute minimum I'd want to have the largest dynamic range).

For Nikons that's true.....but Canon's native ISO has been 100 for quite some time. I wonder if your sharpness issue is due to diffusion from the lens (which smaller sensors have greater diffusion).http://www.clarkvision.com/imagedetail/evaluation-1d2/
