Nikon confirmed to PDNonline that all upcoming new products will be released as scheduled:
"Nikon is actively working to maximize production during this challenging time. As previously announced, availability of the Nikon COOLPIX S4100 and S6100 in the Americas will not be impacted and sales of these products will only be discontinued in some markets. Nikon Inc currently plans to release new products as scheduled."
The only product that could be delayed is Nikon's new mirrorless camera. Wolfgang Lutzky (head of Nikon Austria) indicated back in February that plans for the new mirrorless camera should be revealed in March, which of course did not happen:
"When asked when Nikon would enter this market (i.e. mirrorless), Lutzky referred to the next presentation of financial results in March and mentioned that Nikon’s top managers might lay out their (mirrorless) plans at this occasion."
In July of 2010 Bloomberg interviewed Nikon’s President Makoto Kimura who said that Nikon could introduce their mirrorless camera “any time this fiscal year or the following year” (meaning 2012):
“The new concept model will probably have an enhanced function for video recording and may adopt the so-called mirrorless structure. It could be any time this fiscal year or the following year, as new models are starting to sell.”
