A few months ago I received a tip that the future Nikon Capture NX3 software will be completely rewritten from scratch and will include all Nik plugins except for Color Efex, which will be available as an option. I was never able to verify this rumor. A recent post on the [NR] forum reminded me to post this online (still unverified).
Capture NX2 program is written by Nik software. Back in 2006, Nikon made a “capital investment” in Nik Software. Almost all Nik plugins were recently updated to a 64 bit version. Nik recently announced also a new HDR Efex Pro software. Adding Nik plugins to the future Capture NX3 makes sense, especially if they release a 64 bit version of the software.
