New AF-S Nikkor 50mm ƒ/1.8G lens?

Nikon AF-S Nikkor 50mm ƒ/1.8G

Nikon Imaging USA posted info on a new 50mm ƒ/1.8G lens, only to promptly remove it. What’s behind the erratic behaviour? Thom Hogan adds:

Obviously, someone jumped the gun on Nikon’s Web site. We’ll just chalk it up as another strange tale in Nikon’s long history of strange product marketing.
