Sooooo glad I read this thread and decided to call to check my preorder. I have had one on order at Adorama since 7 Feb, but since then my bank switched the credit card number I used. Of course they didn't tell me the charge didn't go through, but I just fixed it and the order will apparently go out today. That's great because I'll be shooting non-stop for the next 5 days.
The Adorama rep did refer to the lens as being "in stock" so they might actually process regular orders, too.
