Update: I started a forum discussion about the potential issues/bugs with the latest version of Capture NX.
Nikon Capture NX 2.2 now available for download in the US & Canada:
I guess Nikon could not wait till April as previously announced and they released the Nikon Capture NX 2.2 (Win link) update today in Europe (Mac link available here).
A new version Camera Control Pro 2.4.0 is also available for download.
Next, I will check if there are any traces of new bodies or lenses in Capture NX.
