An auction on EBay was advertising the D100 for sale: this was clearly nonsense as the camera is unlikely to be released before June/July. The auction has now been deleted, but I think it's worth mentioning as a warning since there have been previous reports of frauds involving the D1 series cameras.
These folks clearly target the hyper-anxious digital consumers. What other group would even think to search for a camera that has no price or release date on Ebay? Did anyone follow what happened with the F5 auction that had linked images to the website with one guy's Photoshop concept of a digital F5? I don't think I bookmarked the auction.
It's always a good idea to look closely at feedback on Ebay. See if the any trading was all for quick minor auctions. I don't think it's wise to do any significant bidding when the seller has little or no feedback.
This fellow is just illustrating his idea for a digital F5 back, but the ebay auction for a plain old F5 used links to his "digital" F5 Photoshop illustration images. I doubt the owner of the site ever knew of the nefarious use of his ideas.
