See the Nikon website: http://www.nikon.com.au/pagearticle.php?pageid=65-52b9b66212
And note this bit - "Owners of grey items may
not be able to download online software and firmware upgrades available from the Nikon site, due to incompatible serial numbers."
And you can't register on the web in the other countries unless you have an address in that country...a bummer for firmware updates to cameras
