I just got this message when I started Lightroom:
Yes, Adobe Lightroom 3.3 just got released with Nikon D7000 camera support.
Download links: Windows | Mac.
Update: support for Nikon D3100 and P7000 are also part of this update. The new Adobe’s Camera Raw 6.3 can be downloaded here. Adobe Photoshop 12.0.2 was also released: Windows | Mac.
