I don’t see any reference to this on the US Nikon site, but in the UK:
Following the success of our digital line-up over the last seven years, which has resulted in more than 95% of Nikon’s UK business being within the digital area, Nikon Corporation has made the decision to focus management resources on digital cameras in place of film cameras. This decision will allow Nikon to continue to develop products that match the demands of an increasingly competitive market place.
As a result of the new strategy Nikon will discontinue production of all lenses for large format cameras and enlarging lenses with sales of these products ceasing as soon as they run out of stock. This also applies to most of our film camera bodies, interchangeable manual focus lenses and related accessories. Although Nikon anticipates that the products will still be in retail distribution up to Summer 2006.
