Looks like Sideshow goofed on their dates for the shipping info for Darth Vader:
"Orders placed prior to February 19, 2005 are expected to ship the week of February 1st, 2006.
Orders placed from February 19, 2005 and later are expected to begin shipping the week of February 20th, 2006 when we receive our final shipment of these statues."
Since I ordered right on Feb 19/05, it actually doesn't make a difference - it's still going to ship Feb 20/06.
