Earlier today a Nordic retailer leaked specifications and pricing on the Radeon R9 290X, the Battlefield 4 edition that is. NewEgg jumped the gun as well and is listing the Radeon R9 290X. Interestingly enough, the price is much lower then what the Nordic website lists, as you may purchase the product in pre-order for 729.99 USD.
Newegg always list the price a little different, so it is now pretty safe to assume that the Radeon R9 290X pricing will be set at 699 USD. I really want to give props to TPU for discovering this methodology as the price simply was hidden in the HTML code of NewEgg.
BTW it seems that all pre-orders are based on the Battlefield 4 edition, thus you'll be receiving the game with all extension packs and DLC.
