Nikon D600 has been removed from the Minimum Advertised Price (MAP) list by Nikon. This is according to a rumor posted today on Nikon Rumors. Along with the D600, the Nikon D5100 has been removed from the list. This signals to retailers that they may freely advertise the D600 and D5100 at a lower than retail price. By removing the D600 from the MAP list, speculation is that a new Nikon D610 camera could be announced very soon. The camera could end the controversy over dust and oil issues that some D600 users have experienced. It could also mean new features are in the works, placing the D610 at the top of the Holiday wish list for many photography enthusiasts.
