New Amazon delivery date for D4 is here.
I ordered the D4 January 6th. Amazon originally said March 20th release with March 21st delivery date. Of course on March21st I didn't get a camera and Amazon changed the ETA to just out of stock. Amazon CS knew nothing.
This morning I got an email saying March 29 is the new estimated delivery date. I'll post again on the 29th if I actually get a camera.
