(news and commentary)
Inventory must be piling up on Nikon. The latest offer is a D3100 plus both the 18-55mm and 55-200mm DX lenses for US$499.95 with free next day air shipping from the Nikon Online Store. The free shipping is only available today and tomorrow, but the two-lens kit price is available through June 1st.
The fact that there are plentiful D90, D3100, D5100, and D7000 products still available new means that Nikon miscalculated and built too much inventory for demand. At some point, you have to fire sale these things and get them off your balance sheet. I don't think that's the last we've seen of previous generation sales. The real question is when does the problem become so bad that we start seeing aggressive deals on current generation gear?
