Nokia Lumia 920 for $ 450 ?!

According to Engadget , AT & T began to take pre-order on the Nokia Lumia 920 for $ 99.99 with a 2-year contract and $ 449.99 (!!!) without a contract. You can order by the link (instead of 2-year contract, you must select no commitment).
The price from AT & T causes a strong dissonance from the Russian (24 990 rubles).
