Update: this cancelation may not be valid for all countries. The Nikon Coolpix S6100 camera was also canceled in some countries. In the US, both models seems to be available.
Nikon Japan just posted on their website that the Coolpix S4100 camera is "canceled" (not sure about the exact translation) as a result of the earthquake in Japan. In this bulletin Nikon acknowledges that they are experiencing parts and supply difficulties. No other products were mentioned in the statement.
I am not sure what to really think of this announcement - does it mean that this is the only product affected by the earthquake? Are there more similar announcement to follow? Hopefully we will learn more when Nikon announces their yearly financial results tomorrow.
