UPDATE: blow-up of the image (thanks E.C.) - hard to tell what camera this is but as some have already suggested this image is not new and I think I have seen it already somewhere:
There is also a Nikon show in Malaysia from October 14th-18th, 2009 described as "Nikon's highlight event for the year".
As mentioned before, in the US we will have the Photo Plus Expo in New York from October 22nd-24th, 2009.
Introducing new products on October 15th makes a lot of sense.
