Amazon does this stuff all of the time when they can't fulfill on time. I ordered a Star Wars VC Imperial Gunner on 10/08 that was supposed to ship from "Pinnacle Toys and Games" via Amazon. Still haven't received it and have received two of those emails asking me to click on that I "Still Want The Item". FYI that $#!((Y seller shows "Two Left In Stock - Order Soon!" on their listing.
I've had this experience with Amazon before. It's semi-normal.
This is also why I don't commonly order stuff that isn't shipped and held directly by Amazon.
