Amateurphotographer reports another 10% price increase of the Nikon D90 in the UK starting next month (May, 2009). The reason - exchange rate fluctuations. Expect this price increase to trickle-down to other countries as well. Now, the D5000 pricing will not be so close to the D90 price.
According to this post in dpreview, Nikon support confirmed the D90 LV bug "in LV mode the shutterspeed is frozen at the value taken at the moment of activation" and a patch is expected soon.
