Nikon D4, what’s in a name?

This is nearly confirmed, the successor to the very nice Nikon D3 will be named Nikon D4 (and not D3x as was imagined before). The (negative) information comes directly from Chasseurs d’Image and seems very reliable.

I guess it means that Nikon feels this will be a major step forward and not only an upgrade to the existing Nikon D3. Clearly, Nikon is the leading brand in terms of technology leaps this year.
