Look at the news at the Nikon site. The floods last fall in Thailand caused a very large amount of damage to a a large area of Thailand. Nikon expects normal manufacturing levels to be restored at the end of March 2012.
I know this may be a swear word but Comet have got some at some of their stores, where in the uk are you. This is true about the flooding and has caused a bit of a problem with stock. I got mine back in december before the xmas rush. I am in Glasgow and know of a couple of stores that have them....im happy to help if I can
When I got mine (back in November) here in Canada, the sales person told me that the Nikon rep had said that the stocks for everything that come from Thailand would be impacted due to the flooding, and to expect things out of stock. They even ran their Christmas sales in November so they had product - now all the sales are on Canon gear.
