I generally don't comment on beta releases, but ACR 4.6 beta, available on the Adobe Labs site, supports the new P6000 raw format. David Coffin has also updated his dcraw to support it, and several other raw converters are claiming they'll have support for the camera soon, too.
Nikon appears to keep pointing the gun at their foot and pulling the trigger. I simply don't understand the P6000 launch and press releases. Remember, Nikon indicated that it wouldn't be supporting P6000 raw conversion in Capture NX2, or the Macintosh versions of its products. (From the press release: "Capture NX, Capture NX2 and NEF files are not compatible with NRW (RAW) images.")
No Nikon response was made to the many comments and complaints about the new raw format. Now we find out that it's just a different container package, and relatively easily supported. So the question is this: who messed up in Nikon's marketing and product management? Essentially, the mishandling allowed the launch to be completely overridden with negative messages amongst the very group the camera should appeal to. Someone is asleep at the wheel.
So, I guess I'll have to get a P6000 and evaluate it after all (with non-Nikon software ;~).
