Nikon S4100 and S6100 still available says Nikon US
Nikon USA has announced that its Coolpix S4100 and S6100 models will continue to be available to American customers. This follows a statement from Nikon Japan that the recently-introduced S4100 was being withdrawn as a result of component shortages following the earthquake and tsunami in Japan. The withdrawal only affects certain markets, says Nikon USA, and confirmed both models will continue to be available in 'The Americas.' We have not yet heard about European availability.
Nikon USA's statement:
“The Nikon COOLPIX S4100 and S6100 cameras are available in the Americas. As recently reported by Nikon Corporation, sales of these products are being discontinued in some markets however availability of these products in the Americas will not be impacted.”
