Amazon has effed me over the last several times. My pre-orders of Brand New: Deja, High On Fire: Luminiferous (advertised at $7.99 only!) and AAR: Self-Titled all sat there well past the release date. All it said was temporarily out of stock.
I have pre-ordered this as well, but will probably order from the Rammstein webshop when it goes up.
