I've got to say I'm in agreement with the general sentiment of this thread. I've said this many times: given that we have very little information to go on, most of what people are saying is, in my opinion, speculative at best. I wouldn't put much stock in the DR talk and such until DxO gets their hands on both these cameras to do proper testing. Until then, I'm not making any conclusions one way or another.
I'd be curious to know what buzz is going around the Nikon forums, whether they're all whining about the D800.
I agree, there's far too much hysteria going around when the information just isn't there to support it.
