Nikon has discontinued its recently-announced Coolpix S6100 and Coolpix S4100 in Asia markets, citing that the earthquake in Japan has lead to production and supply issues with the camera. No word yet on whether there is a similar effect in the US and other markets for these or other Nikon models.
For more info, see the statement issued by Nikon below.
Nikon Coolpix S6100 and S4100 Announcement
Nikon has decided not to embark on sales of the COOLPIX S6100 and COOLPIX S4100, which were announced on February 9, 2011.
Though these two models were announced in February, it has been determined that steady production and supply of these models will be difficult. For this reason, sales of the two cameras have been discontinued in Asia*.
We sincerely apologize to all those affected by this decision, and especially to those who had intended to purchase the camera, as well as our retailers and others whose business will be affected by the inconvenience this decision may cause.
