Ormai sembra "ufficiale", verso la fine dell'anno Nikon dovrebbe presentare la nuova D400 che andrà a sostituire la sorella minore D300, e novità salienti potrebbero essere:

Sensore da circa 14.8 megapixel CMOS mentre non è chiaro se sarà a formato pieno (FX) o a formato ridotto (DX), avrà quasi certamente le funzionalità video già viste nella D90, ma più simili a quelle della Canon 5D mark II (alta definizione 1080p 24 fps - stereo).

Questo il thread apparso sul sito Nikon Rumors da parte di un utente anonimo:
