wskb: Ahhh, so it is 36M! Don't need that then... though I'm sure lots will!
(by the way the 4X photons isn't exactly true because of how Bayes filters work, but I'm talking about the principle)
Methinks tkpenalty doesn't understand how light gathering works. If you downsize/normalize at 50% from 36MP to 9MP, of course you'd have lower noise, as nicolaiecostel said. You would be basing the picture on 4X the photons per pixel by downsizing, so you'd get better signal to noise ratio.
Peter G: Deleting the AA filter from a camera at the factory shouldn't increase it's price.
The D800E doesn't simply delete the AA filter, but rather uses the 2nd pass to undo the first. You should look up the technical details.
As to price, I can't really speak to that. I'm unclear on whether this is a luxury feature, or whether it technically costs more.
dspphotos: Most definitely go for a non-AA version for me... Having seen how non-AA cameras look, you'd be silly not to consider it if you're not shooting images that are very prone to moire.
But that just confuses digital artifacts for apparent sharpness. If you want that, you can do it just as easily in post. What you can't easily fix is certain types of moire.
Sean65: That interesting because 90% of the 'experts' passing comment on this camera have probably never even printed a picture let alone a large or very large picture. I'd say most manufacturers are missing the point that the majority of photographers don't even print pictures anymore and would need nothing more than a 4MP camera.
Can't wait to see some sample of the higher ISO pictures, could be interesting.
Mtsuoka, agree with HiRez on this. If you composed the photograph properly, why would you need to do significant cropping?
