The D3X is certainly something to lust after, although sensitivity to low light and quality glass trump "pixel count" for serious storm photography. The D3 and D700 are still the royalty of low light performance. Now, if you are a serious bird photography, you need all the pixels you can get your hands on for cropping purposes, etc. I agree with Ryan that Nikon has at the very least reached Canon's level of superiority in the DSLR world. Canon still has an advantage over Nikon in some areas, but Nikon IMHO has probably passed Canon (at least now) in areas like low light performance.
