Sony Playstation 4: 400 MUSD Revenue From Preorders Alone

We see such huge preorder revenue numbers once in a while - we spotted this stat today, that Sony has preorders for more than a million units of the Playtation 4 - at 399 USD, that works out to a revenue of 400 Million USD (Source)

From a magnitude standpoint, weekend sales of iPhones and some Samsung Phones could easily beat these numbers, but these are definitely huge numbers for Sony.
