Nikon is circulating odd cards that give out very little info (see image to right - click to enlarge). Well, the assumption is that the mailers are coming from Nikon, we don't really know for sure since they aren't marked by any company. They are high quality direct marketing pieces and appear to be a count down starting with the number 8. A number 7 appeared now too.
The colors suggest it's from Nikon and the fact that the people receiving them are Nikon owners. These are appearing in France.
It's speculated that they are the precursor to the rumored EVIL cameras the Nikon rumor forums have been chatting about. This would be a huge development, and quite exciting.
Of course perhaps it's the lead-up to the much anticipated D800. Who knows, but I'm excited regardless. New stuff is always exciting, don't you think?
