I just saw this on fredmiranda.com - it seems that Nikon has reached a settlement on the D600 class action lawsuit and people participating in the lawsuit have received this email with instructions on how to get a new D610 camera ($1,896.95):
As a result of your involvement in the Nikon D600 camera lawsuit, Nikon has offered to immediately provide you with a new D610 camera in exchange for settling your individual claim.
In order to accept this settlement offer and receive a D610 you must complete the following steps:
1. Complete and sign the attached Qualifying Statement, Short Form Release, and Confidentiality Agreement.
2. Register your D600 camera at the following link: https://support.nikonusa.com/ci/documents/detail/5/144/12/33a9814ba32973bc88a6c149468e888c2cd1adf5
3. After registering your D600 camera, you will be prompted to create and print a pre-paid UPS Return Label and packing slip.
4. Pack your defective D600 camera, packing slip, and the original signed copy of your Qualifying Statement, Short Form Release, and Confidentiality Agreement in a box, and affix the UPS Return Label. Drop the box off at any UPS facility. (Visit https://www.ups.com/dropoff for hours and locations.) You may also arrange to have your shipment collected by a UPS driver.
5. Once Nikon receives your D600 and the required documents they will mail you a replacement D610 camera.
Please send only your D600 camera, packing slip, and the Qualifying Statement, Short Form Release, and Confidentiality Agreement to this address. When shipping, please secure the D600 camera in a plastic bag inside the shipping box with quality packing material on all sides of the D600 camera. Your D600 must be received in satisfactory working order. Do not include any lenses, batteries, memory cards or other accessories. Also please ensure that your name and address are printed legibly on the Qualifying Statement, Short Form Release, and Confidentiality Agreement.
This settlement offer is completely voluntary. You have until November 30, 2014 to accept this offer. Anyone who chooses not to participate will retain their right to pursue further legal action against Nikon. However, as a result of this offer we will no longer be pursuing legal action against Nikon for its defective D600 cameras.
D600 owners who did not contact our law firm may avail themselves of Nikon’s updated D600 repair and replacement program.
It is critical to note that you must keep this resolution completely confidential, which you agree to do by signing the attached Confidentiality Agreement. Any dissemination of the information contained in this email or the settlement offer may render you ineligible to receive a D610. Please refrain from posting any information about the settlement offer or your replacement D610 on any websites, and refrain from discussing the settlement offer with any other individuals.
Thank you for contacting our law firm and for your participation in the case. Please let us know if you have any questions, and should you need legal representation in the future please do not hesitate to contact us.
Update: several readers asked me how to take advantage of this settlement. My understanding is that if you did not register in advance with the law firm (I posted the links before, but now those pages are no longer available), you cannot be part of the lawsuit. In that case you can try replacing your camera directly with Nikon.
