Here in Aust I was told in July it would be end of the year before regular supplies come in. All the stores said they had 4 months worth of back orders but then one major retailer advertised in their catalogue so I rang them and they actually had a "spare" one in stock So it's worth just ringing around every so often as you never know.
I also bought a monopod and UV filter, so was able to knock the price down a little too
Called in at my local Nikon dealer and they had two in stock,decided to part with a couple of old friends though rather than use the credit card or wait,he still has one in stock and does mail order if any one wants one £945
