The end of an era: the Sigma APO 200-500mm f/2.8 (Bigma) lens is already discontinued

It seems that the Sigma APO 200-500mm f/2.8 (Bigma) lens is already discontinued:

Update: When some random editor emails the Sigma Public Relations person, who has no clue what is going on in Japan, and tells you that the lens is not discontinued, you have to ask yourself: why are all those stores not willing to a list and sell a $25k lens? Do you think B&H will remove the listing of a $25k lens if they have the chance to sell one? But this is what happens when you get random people who have no clue how the industry works and make them "editors". How clueless you must be to believe what a company's PR person is telling you? Remember Olympus?

The lens was initially announced in April 2008. The end of an era (the DSLR era).
